To: u-boot
For boards such as the MIPS Malta with an FPGA core card it is desirable
to be able to detect the L1 cache sizes at runtime, since they are not
dependant upon the board but on the FPGA bitstream in use. This patch
performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are
not defined by the board configuration. In cases where the sizes are
detected this patch also removes the restriction that the I-cache &
D-cache line sizes must be the same, as this is not necessarily true.
If the cache sizes are defined by a configuration then they will be
hardcoded as before, so this patch will not add overhead to such
boards.

Fix up the code to match Documentation/CodingStyle. This is mostly
removing extraneous spaces.
No functional change is intended.

Ensure that the view of memory from the CPU & the ethernet controller is
coherent at the various points where they exchange data. This prevents
stale data from being transmitted or received, and prevents the driver
from getting stuck waiting for the ethernet controller to update
descriptors when in reality it has but the old values are being read
from cache.

On relatively slow boards (such as the MIPS Malta with an FPGA core
card) it can be extremely common for transmits to underflow - to the
point where it appears they simply do not work at all. Setting the
NOUFLO bit causes the ethernet controller to not begin transmission on
the wire until a transmit start point is reached. Setting that transmit
start point to the full packet will cause the controller to only
transmit the packet once it has buffered it entirely thus preventing any
transmit underflows from occuring and allowing the controller to
function on slower boards.

This patch simply #ifdef's out the C-specific parts of pci.h when it is
included by an assembly file. This will allow the macros it contains to
be used from assembly source as will be done in a followup commit adding
support for more modern MIPS Malta boards.

This is in preparation for adapting this board to function correctly on
a physical MIPS Malta board. The board is moved into an "imgtec" vendor
directory at the same time in order to ready us for any other boards
supported by Imagination in the future.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>
---
Changes in v2:
- move to an imgtec vendor directory to reduce churn should other
Imagination boards be added later
- enable rename detection for the patch

The changes in bootm.c are not strictly related to the rename. It would be
better to do these in a separate patch.

This change also should be done in a separate patch. Additionaly,
CONFIG_QEMU_MALTA is used in arch/mips/cpu/mips32/start.S so it should be
changed as well.

I disagree. The board was renamed from qemu-malta to malta, so it makes
perfect sense to change CONFIG_QEMU_MALTA to CONFIG_MALTA and
mips_boot_qemu_malta to mips_boot_malta at the same time. These changes
are purely a part of the rename, made for consistency.

Again it's part of the rename so I don't agree about splitting to a
separate patch, but you're right about start.S - I missed that and
didn't notice because I'm not running an old QEMU.

I agree that it is related to the rename. However renaming the
mips_boot_qemu_malta constant is a simple cleanup which can be done in a
preceding patch. The same is true for the CONFIG_QEMU_MALTA->CONFIG_MALTA
conversion.
In general, renaming a file and altering that within the same patch makes the
review harder.

And for more complex changes I might agree, but only a single file is
both renamed and modified by this patch: include/configs/qemu-malta.h =>
include/configs/malta.h. Only a single line is modified within that
file, changing CONFIG_QEMU_MALTA to CONFIG_MALTA. I don't think it's
very difficult to understand and I think splitting it would be overkill.
So if Daniel tells me (v3 of) this patch isn't getting in as-is then
I'll split it, but short of that I'm not changing it.
Thanks,
Paul

Actually I don't care. It is one logical change which is also trivial
and bisectable. If you want, you could move the renaming of
CONFIG_QEMU_MALTA and mips_boot_qemu_malta to a separate patch.

I don't say that it is hard to understand that. Simply the first two version of
the patch introduced a regression on older qemu version due to the missing
change in mips32/start.S, and it took some time to me to figure out why a rename
patch causes such thing. If it would have been a separate change, it would have
been obvious.

This is in preparation for adapting this board to function correctly on
a physical MIPS Malta board. The board is moved into an "imgtec" vendor
directory at the same time in order to ready us for any other boards
supported by Imagination in the future.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>

Changes in v3:
- modify a missed CONFIG_QEMU_MALTA in arch/mips/cpu/mips32/start.S
which would affect old QEMU builds
Changes in v2:
- move to an imgtec vendor directory to reduce churn should other
Imagination boards be added later
- enable rename detection for the patch

On a real Malta the Super I/O needs to be configured before we are able
to access the UARTs. This patch performs that configuration, setting up
the UARTs in the same way that YAMON would.

From: Paul Burton @ 2013-10-23 10:07 UTC (permalink / raw)
To: u-boot
This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU, which seems to be broken but boots as far as it did before
this patch (including correctly printing CoreLV on serial).

To: u-boot
2013/10/23 Paul Burton <paul.burton@imgtec.com>:
> This patch adds support for running on Malta boards using coreFPGA6
> core cards, including support for the msc01 system controller used
> with them. The system controller is detected at runtime allowing one
> U-boot binary to run on a Malta with either.
>
> Due to the PCI I/O base differing between Maltas using gt64120 & msc01
> system controllers, the UART setup is modified slightly. A second UART
> is added so that there is one pointing at the correct address for each
> system controller. The Malta board then defines its own
> default_serial_console function to select the correct one at runtime.
> The incorrect UART will simply not function.
>
> Tested on:
> - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
> with and without an L2 cache.
> - QEMU, which seems to be broken but boots as far as it did before
> this patch (including correctly printing CoreLV on serial).

Contrary to the kernel U-Boot code must not use base + offset in IO
primitives. Registers should be implemented with a struct.
For example:
struct foobar_regs {
u32 foo;
u32 bar;
};
struct foobar_regs *regs = (struct foobar_regs *)CKSEG1ADDR(FOOBAR_BASE);
u32 val = __raw_readl(®s->foo);

1 sibling, 1 reply; 35+ messages in thread
From: Paul Burton @ 2013-10-24 9:33 UTC (permalink / raw)
To: u-boot
This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU, which seems to be broken but boots as far as it did before
this patch (including correctly printing CoreLV on serial).
Signed-off-by: Paul Burton <paul.burton@imgtec.com>

Changes in v2:
- rebased after malta moved to board/imgtec/malta
- removed unused status variable from msc01_config_access

It is indeed broken with qemu 1.6.1. However it boots fine on older qemu
versions if the memory size is explicitly set to 256M with the '-m 256' option.
Tested with qemu versions 1.2.2, 1.4.2 and 1.5.3.

Could you point me to somewhere stating that? (and why?) I can't find
anything in README and I can see plenty of code using base+offset
already in U-boot. In this case the assembly in lowlevel_init.S has to
access various registers so using the offsets in C means I don't need to
duplicate the information in both struct & offset macro forms. I don't
mind too much if it's a rule but I'd like to see some
justification/reasoning before I change this.
Thanks for the review,
Paul

Displaying a message on the LCD screen is a simple yet effective way to
show the user that the board has booted successfully.

This model of the pcnet is used in current Malta boards, at least in the
Malta-R rev 3. Enable support for it.
The Malta also has the ethernet controller PROM containing its MAC
address, so enable support for that in order to read that MAC address.
DHCP is a very useful feature to have available for many networks,
enable support for it also.

These will now be detected at runtime, allowing a single U-boot
configuration to function correctly with different bitstreams. Without
this you may need to re-configure, re-build and re-flash U-boot to your
Malta if you flash a new bitstream with a different cache configuration
to your old bitstream.

Malta boards may be used with cores which support L2 caches, however
U-boot does not yet support L2 cache for MIPS. Thus for the moment we'll
disable L2 caches by setting the L2B bit in Config2. This is specific to
MTI/Imagination MIPS cores which is why this is done for the Malta board
rather than generically.

This patch adds a script which may be used with MIPS Navigator Console
and a MIPS Nagivator Probe in order to flash U-boot to a MIPS Malta
development board.
Please see the newly added doc/README.malta for usage instructions.

+MIPS Malta board
+
+How to flash using a MIPS Navigator Probe:
+
+ - Ensure that your Malta has jumper JP1 fitted. Without this jumper you will
+ be unable to flash your Malta using a Navigator Probe.
+
+ - Connect Navigator Console to your probe and Malta as usual.
+
+ - Within Navigator Console run the following commands:
+
+ source /path/to/u-boot/board/malta/flash-malta-boot.tcl
+ reset
+ flash-boot /path/to/u-boot/u-boot.bin
+
+ - You should now be able to reboot your Malta to a U-boot shell.
