Jc,
Wolfgang is the best person to answer your question.
Also read this http://lists.denx.de/pipermail/u-boot/2009-September/059794.html
The way I look at things, any new patches or files with such references are going to get comments from him.
I will be submitting patches based on his suggestion above so just removing such references to make things consistent across all DaVinci SOCs.
As I said before if the concerned header files are removed at least DaVinci SOCs will not be affected.
Thanks, Sandeep

I saw this comment: "Also i gather from e-mails on the list that Wolfgang does not like these references to "SZ_xx". Maybe that discussion took place before I joined the list.
If he wants it that way, fine. But that doesn't explain the "why". What's so offensive about the SZ_* defines?

Jc,
Did you read what I wrote below the --- line in the patch itself?
Wolfgang wants to get rid of these references. He expressed this some time back.
If he decides to get rid of this file altogether this will lead to compilation failures.
Thanks,
Sandeep

Why is this change being made at all? Seems a lot more awkward to define (1 << 20) than SZ_1MB. SZ_1MB reads a lot easier.

Dear s-paulraj@ti.commailto:s-paulraj@ti.com,
In message <1252434246-19517-1-git-send-email-s-paulraj@ti.commailto:1252434246-19517-1-git-send-email-s-paulraj@ti.com> you wrote:

This patch removes the asm/sizes.h header file from being included in the DaVinci SOC configs. References to SZ_xx have been replaced by appropriate bit shifted values.
Signed-off-by: Sandeep Paulraj <s-paulraj@ti.commailto:s-paulraj@ti.com>
Note that this patch actually changes the configuration:
--- a/include/configs/davinci_dm355evm.h +++ b/include/configs/davinci_dm355evm.h
...
/* U-Boot memory configuration */ -#define CONFIG_STACKSIZE SZ_256K /* regular stack */ -#define CONFIG_SYS_MALLOC_LEN SZ_512K /* malloc()
arena */
+#define CONFIG_STACKSIZE (256 << 10) /* 256 KiB */ +#define CONFIG_SYS_MALLOC_LEN (1 << 20) /* 1 MiB*/
as it increases the malloc() arena size form 512 to 1024 KiB.
Assuming this was done intentionally:
[Sandeep] Yes this was intentional because for NANDs with large block sizes(256 KiB), if this is not increased we will get "out of memory" errors.
Acked-by: Wolfgang Denk <wd@denx.demailto:wd@denx.de>
Then this change needs to be a separate patch.
