[U-Boot] [PATCH 00/17]: ARM: SPL: Make more generic, merge DaVinci and OMAP

[U-Boot] [PATCH 00/17]: ARM: SPL: Make more generic, merge DaVinci and OMAP

[Tom Rini]

Hey all,

The following patch series merges the davinci and omap-common SPL
frameworks into a single framework, CONFIG_SPL_FRAMEWORK along with a
few small cleanups to the code to make it a little smaller and more
flexible.  The end result is that davinci can now opt in on
SPL-boots-Linux by just setting the right defines and other platforms
would just need to adapt to this framework.  In my testing, davinci
gains between 300 and 700 bytes for this (not enabling the SPL OS
feature) and omap4/5/etc lose just a little bit (from the printf->puts
changes).  I've tested this on omap3_beagle (xM and classic) and
omap4_panda.  I don't have any davinci platforms that were previously
using SPL so I can't boot-test those changes but since everyone sets
CONFIG_SPL_MAX_SIZE, we're OK in that department.

To make this series easier to test I've placed it on
http://github.com/trini/u-boot WIP/spl-improvements

I've looked a little into re-reducing the size and the biggest problem I
see is that SPI a lot of informational prints that we don't need,
strictly speaking, but are nice in a normal U-Boot context.  I'm unsure
of the best way to quiet these as I don't like the idea of sprinkling
#ifndef CONFIG_SPL_BUILD in random places.

[U-Boot] [PATCH 02/17] omap-common: SPL: Add CONFIG_SPL_DISPLAY_PRINT / spl_display_print()

[Tom Rini]

Only omap4/5 currently have a meaningful set of display text and overo
had been adding a function to display nothing.  Change how this works to
be opt-in and only turned on for omap4/5 now.

[U-Boot] [PATCH 03/17] ARM: SPL: Move the omap SPL framework to arch/arm/lib

[Tom Rini]

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the arch/arm/lib SPL
framework, enable on all of the previously using boards.

[U-Boot] [PATCH 04/17] Makefile: Move SPL files to clobber, remove from clean

[Tom Rini]

The 'clean' target has been removing all of spl but not u-boot itself.
For consistency and ease of testing, only remove SPL binaries / maps in
the clobber target, just like for full U-Boot

This detection code doesn't (and can't) do anything currently, so
remove.

[U-Boot] [PATCH 09/17] ARM: SPL: Only call mem_malloc_init if configured

[Tom Rini]

We can only attempt to setup a malloc pool if
CONFIG_SYS_SPL_MALLOC_START is defined, and not all boards require it.
Make the call depend on the define.

[U-Boot] [PATCH 12/17] ARM: SPL: Clean up spl.c / spl_nand.c slightly

[Tom Rini]

- Remove includes we don't need
- Switch some printf statements to puts
- Convert some printf statements to debug, introduce new puts statements
  - In most cases saying just "No mkimage signature, assuming
    u-boot.bin" or similar is sufficient.  This also means the non-DEBUG
    case doesn't need printf, in the core of SPL.
  - The other case here is that PLAIN_VERSION provided what we wanted
    already, so just use it.

- Convert the non-relocation part of board_init_f to spl_board_init,
  turn on CONFIG_SPL_BOARD_INIT in the configs.
- Remove duplicated code.
- Add spl_boot_device() that returns the statically chosen boot device.

[U-Boot] [PATCH 16/17] SPL: Enhance drivers/mtd/nand/nand_spl_load.c

[Tom Rini]

Takes the load function from arch/arm/lib/spl_nand.c instead.  This will
allow for easier integration of SPL-boots-Linux code on other arches.
Kill off CONFIG_SPL_NAND_LOAD as a separate option.

Making SPL more generic is great. So moving these files out of the
omap-common directory is the way to go. But your approach moves them to
arch/arm/lib, restricting it only to ARM. Wouldn't it be possible to
move it into an even more common location, so that other archs may also
benefit from it?

I'm asking, since I'm currently working on an PowerPC based board which
shall also use the SPL OS booting feature (Falcon boot).

Are the files ARM specific (I'm just starting looking into them right now)?

Thanks,
Stefan

Oh, I was working on the same concept to make SPL available for other
SOCs. I can get through your patches, we get surely the same conflict
between architecture.

In my attempt I moved files from arch/arm/cpu/armv7/omap-common/ to
common. This is because to make it available to all SOCs, not only
armv7. What do you think about ? I would like to add an example with an
arm1136 (MX35).

This is a conflict I got. This file should be generic code, and should
not have reference to a specific SOC or SOC family, as omap here. So I
have added a include/spl.h with only the SPL relevant part, dropping
other OMAP specific from this file (I see you did the same with
omap_boot_device and omap_boot_mode).


> +#include <asm/arch/mmc_host_def.h>

As far as I have understood, this is only for MMCSD_SECTOR_SIZE, that
can be moved into another header file. Not all SOCs have
asm/arch/mmc_host_def.h

Both files are OMAP specific

And this is also omap specific. Replaced by soc_boot_device ?

This also does not work with other SOCs, where there is not a gpmc init.
My idea was to add here a soc specific function, where gpmc_init and
nand_init can be called.

Agree, mem_malloc_init should be not always called. However, how are the
dependencies with other SPL configuration ? I think (but I can be wrong)
that we need it if CONFIG_SPL_LIBDISK_SUPPORT or CONFIG_SPL_FAT_SUPPORT
are set. Should we add them to your #ifdef case ?

Stefano

In theory, these should be fine on other arches.  I'm just hesitant to
call these common and put them in common/ without someone else doing the
work of making sure they really are usable elsewhere.  Sounds like about
now would be the time to try, so for v2 I can move them to common/spl.c
common/spl_ymodem.c and drivers/mmc/spl_mmc.c (to match
drivers/mtd/nand/nand_spl* and drivers/mtd/spi/spi_spl*).

Yes, mandating what the asm/ mmc header file names should be is
something I've thought about but not had to step on, yet.

My goal with this series, and part of why I added CONFIG_SPL_FRAMEWORK
was that indeed, there's a lot of omap-isms in the code at the start.  I
believe by the end of the series they're all removed and the code is
common.  If it's a concern I can re-work things so that the move is one
of the last steps.

I think until we have Kconfig-style dependencies available, there's
going to be a certain amount of pain here.  We should probably add to
docs/README.SPL that SPL_FAT_SUPPORT depends on the malloc pool and the
defines that calls for (since there's a few of them not referenced right
were we call mem_malloc_init).

Yes, please do. I'll work on the powerpc integration of this SPL stuff then.

No, it is not a problem. I am setting on top of your tree and it looks
great.

[U-Boot] [PATCH 15/17] ARM: SPL: Convert davinci to CONFIG_SPL_FRAMEWORK

[Christian Riesch]

Hi Tom,
I tested the entire patchset with the da850evm booting from SPI flash
with SPL (make da850evm_config && make u-boot.ais).

I had to add defines for mem_malloc_init to make it work, please see
my comment below.

Please add

#define CONFIG_SYS_SPL_MALLOC_START (CONFIG_SYS_TEXT_BASE -
CONFIG_SYS_MALLOC_LEN)
#define CONFIG_SYS_SPL_MALLOC_SIZE CONFIG_SYS_MALLOC_LEN

here, booting from SPI requires malloc.

Apart from that it works great, I like it :-)
Thank you!

I would have complained about the loss of a small CONFIG_SPL_NAND_LOAD,
if I hadn't found that moving it into the equivalent of
nand_spl_simple.c resulted in a smaller binary. :-P
