[U-Boot] [PATCH 1/2] mpc8308: support for Freescale MPC8308 cpu

[Ilya Yanok]

This patch adds basic support for Freescale MPC8308 CPU. Serial ports,
NOR flash and integrated Ethernet controllers are supported.
PCI Express is also supported. eSDHC, NAND and USB may work but aren't
tested (using ULPI PHY requires additional patch).

Would it make sense to write this as:

And: why do we need the #ifdef? Unused defines should not hurt?

	#define SCCR_SDHCCM_MASK	0x0c000000	/* is it a mask? */
	#define SCCR_SDHCCM_SHIFT	26
	#define SCCR_SDHCCM(arg)	((arg)<<SCCR_SDHCCM_SHIFT)

Ah, I see you just follow precedent code. If Kim accepts this, I'm
fine with it, too.

Do we need that #ifdef? Ok, the #defines don't apply to the 8308, but
do they hurt if they are just there, unused?

Well, it seems to be safer not to have unused defines so that you can't 
erroneously use some define not applicable for current CPU, but if you 
wish I'll remove these ifdefs.

Applied.

Thanks,

[U-Boot] [PATCH 2/2] MPC8308ERDB: minimal support for devboard from Freescale

[Ilya Yanok]

This patch provides support for MPC8308ERDB development board from
Freescale with a minimal set of features:
 Dual UART is supported
 NOR flash is supported
 Both TSEC Ethernet controllers are supported
 PCI Express initialization is supported

The following features are enabled in configuration but not fully tested:
 I2C (used to get the board revision)
 I2C-connected RTC
 VSC7385 switch

Signed-off-by: Ilya Yanok <yanok@emcraft.com>

NAK. Please rebase your code against the "next" branch. We don't
accept any board entries to the top level Makefile any more. Please
add to boards.cfg instead.

I think it's wrong to ignore the return code here.

That's for making board silent then it comes out of sleep (not printing 
version info, checkcpu() output and so on). Actually I've not tested 
sleep/wakeup functionality but the code looks correct.

What makes you think so? What can we do with the return code here? Print 
warning? If we return error from board_eth_init() calling code will call 
cpu_eth_init() again which is useless as we have already called it.

My understanding is that pci_eth_init() and board_eth_init() return
the number of NIC's found - should that number not include the number
of successfully initialized TSECs?

Yes, print a warning if < 0.  As you've noticed, returning -1 wouldn't 
be good.  I'm not aware of a U-boot policy for handling hardware 
problems other than printf.

Yes, please.  Something like:

int board_eth_init(bd_t *bis)
{
     int rc, num_if = 0;
     if ((rc = cpu_eth_init(bis)) >= 0)
     {
         num_if += rc;
     } else {
         print error message
     }
     if ((rc = pci_eth_init(bis)) >= 0)
     {
         num_if += rc;
     } else {
         print error message
     }
     return num_if;
}

I'm working on changing net/eth.c to be less kludgy, but am having a 
hard time setting up my test bed.  Hopefully in the next few days.

Actually I thought that controllers missing in the "NET: " line would be 
enough but I'll add a warning if you ask.

Ok. I get your point. Actually, as for now code in net/eth.c just checks 
board_eth_init() value to be negative or not so there is no difference 
between different non-negative values. But I'll do it like Ben asked.

I don't see the 8308 being a member of the 831x family; e.g., upper
spridr bits are 0x810, which don't match those of 831x: 0x80B.
Please introduce a new CONFIG_MPC830x.

is the BDI overriding the RCW in this case?  it's not clear..

Yes, I've already done this.

Actually I've noticed this myself... But 8308 has many things common 
with 831x and I'm not sure if there is a family of 830x (I can see only 
8308 on Freescale website).

Well, I'll do as you propose.

Yes, my default BDI configuration overrides RCW with 0xa0606c00 
0x44060000 (with HRCWH_PCI_HOST and HRCWH_PCI1_ARBITER_ENABLE bits set) 
to be able to program empty flash.
My test sequence is as follows:
0. I had BDI overriding RCW and programmed U-Boot with the same RCW values.
1. I compiled new U-Boot image without HRCWH_PCI* bits and reflashed it 
from U-Boot itself.
2. Then I rebooted the board with the U-Boot 'reset' command. Everything 
works fine.
3. Reseted the board with 'reset run' command from the BDI. Everything 
works well too (recall that BDI is configured to override RCW with old 
value).
4. Then I've changed BDI configuration disabling the RCW override. 
Everything works.
5. But if I configure BDI to override RCW with new value (without 
HRCWH_PCI* bits) I can't see anything on serial console after reset (but 
it looks like U-Boot is started correctly, at least execution address 
looks correct).

hmm, if it's only on soft-resets, can you try adding
HID0_ENABLE_INSTRUCTION_CACHE to CONFIG_SYS_HID0_INIT in addition to
_FINAL?  Some cache state is preserved over a soft-reset...

Just from my experience on few other boards, this could be a DDR
configuration issue.
Can you try to run at lower frequencies?..Or may be playing with DDR
controller timings.

turning icache on early causes a different pattern of bus accesses when
fetching code, and this might trigger bus accesses that interfere with
code that sets bus configuration registers, such as the acr.  Can you
test this patch please?:

Oops?? Why do we need a new file, with a new function, does nothing
else but calling another funtion, and that gets used just a single
time?

Drop this wrapper!

Do we need __raw_readl()? Why would in_be32() not work?

> +	single_cline_write(&im->arbiter.acr, acr_val & (val & ~acr_mask));

Make this:

	out_be32(&im->arbiter.acr, acr_val & (val & ~acr_mask));

Ah! I guess this is worth a comment?  But should we not rather aligh
the in_* and out_* functions then?

What is the exact use case when such alignment might be needed?  Can
you guarantee that it's only with this specific register access, and
only for write accesses?

Best regards,

Wolfgang Denk

Unfortunately this patch doesn't help too...

Thanks for your efforts!

This issue turned to be BDI related (I can't reproduce it with BDI 
detached).

Sorry for inconvenience.

Regards, Ilya.

[U-Boot] [PATCH 2/2] MPC8308ERDB: minimal support for devboard from Freescale

[Ilya Yanok]

This patch provides support for MPC8308ERDB development board from
Freescale with a minimal set of features:
 Dual UART is supported
 NOR flash is supported
 Both TSEC Ethernet controllers are supported
 PCI Express initialization is supported

The following features are enabled in configuration but not fully tested:
 I2C (used to get the board revision)
 I2C-connected RTC
 VSC7385 switch

There is one (hopefully) minor issue: on soft reset the board sometimes
resets twice. I've not managed to find the fix for this problem yet.
As a workaround instruction cache can be disabled.

[U-Boot] [PATCH 2/2] MPC8308ERDB: minimal support for devboard from Freescale

so, according to this document:

http://cache.freescale.com/files/32bit/doc/user_guide/MPC8308RDBUG.pdf

the board name is just 'mpc8308rdb', not 'mpc8308erdb'.  AFAICT, there
is no version of the 8308 that has an 'E'ncryption unit, so the name
should probably be changed.

apologies for not seeing this earlier...

Well, actually I saw this myself... but the board is named MPC8308ERDB 
in Freescale BSP so I didn't change this name.
Ok, I'll fix this and repost the patch.

Regards, Ilya.

[U-Boot] [PATCH 2/2] MPC8308RDB: minimal support for devboard from Freescale

[Ilya Yanok]

This patch provides support for MPC8308RDB development board from
Freescale with a minimal set of features:
 Dual UART is supported
 NOR flash is supported
 Both TSEC Ethernet controllers are supported
 PCI Express initialization is supported

The following features are enabled in configuration but not fully tested:
 I2C (used to get the board revision)
 I2C-connected RTC
 VSC7385 switch

There is one (hopefully) minor issue: on soft reset the board sometimes
resets twice. I've not managed to find the fix for this problem yet.
As a workaround instruction cache can be disabled.
