To: u-boot
Hello
This patch brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)

From: David Müller @ 2011-01-11 7:41 UTC (permalink / raw)
To: u-boot
This patch brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
- remove the unneeded config.mk file

NAK. I'm not going to review that. Please stick to the rules.
When submitting a new version of the patch you are supposed to descibe
what has been changed. For details please see
http://www.denx.de/wiki/view/U-Boot/Patches#Sending_updated_patch_versions
Best regards,
Wolfgang Denk

This patch brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
- remove the unneeded config.mk file

This patch serie brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
- remove the unneeded config.mk file

Hi David,
It'd be good to include "smdk2410" in this patch titles, eg "smdk2410:
Various cleanups/code style fixes". or "arm: smdk2410: Various..."
Without the prefix, its unclear what code these patches affect, and
somewhat implies you are changing common code.
<snip>
> -#define CONFIG_RTC_S3C24X0 1
> +#define CONFIG_RTC_S3C24X0
Looks like there are a number of tabs in odd locations, it'd be nice to
clean those up while you're modifying this file.
Best,
Peter

This patch serie brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
- remove the unneeded config.mk file

IMHO "Zero" should be correct with activated ARM reloc.

Excerpt from doc/README.arm-relocation:
maybe adapt CONFIG_SYS_TEXT_BASE (this must be checked from board
maintainers)
This *must* be done for boards, which boot from NOR flash
The SMDK2410 is booting from NOR flash (at least it is currently
configured that way) and flash is mapped at address 0.

This patch serie brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
- remove the unneeded config.mk file
- various cleanups/code style fixes
