Patch fixes bug for clearing the bss section

Hi,
There is a bug in the code of clearing the bss section for processor i386.(File: cpu/i386/start.S)
In the code, bss_start addr (starting addr of bss section) is put into the register %eax, but the code which clears the bss section refers to the addr pointed by %edi.

This patch fixes this bug by putting bss_start into %edi register. -------------- next part --------------

Did you test the code in the u-boot-testing repository? I did not receive any feedback from you (nor any form others).

Hi Wolfgang Denk,

I tested my patches in u-boot-testing
1. Clearing of bss section patch and
2. Sata patch.

Clearing of bss section patch has no issues.
But with sata patch, got compilation warning: fuinction proto-type mismatch between block_read and sata_read.

This is becuase i had been working on u-boot downloaded on feb-15th. And on Apr-13th, patch "Fix use of "void *" for block dev read/write buffer pointers" has been applied, which has changed the proto-type of block_read function.

I will bring these changes to my patch. And after testing , i will re-submit the patch.

Thanks,
