[U-Boot-Users] [PATCH] Change to sequoia clock speed
U-Boot users and Stefan:
The AMCC Secquoia board has been changed in a new revision from using a 33.000 MHz clock to a 33.333 MHz system clock. A bit in the CPLD indicates the difference. This patch reads that bit and uses the correct clock speed for the board. This code is backward compatable will all prior boards. All prior boards will be read as 33.000.
The patch is attached.

I applied the patch with small modifications to the u-boot-ppc4xx repository.
Thanks.

It appears that in the process one of the '3's got dropped. A patch is attached.
Ah, yes sorry about that. Thanks for spotting.
I applied your fix to the u-boot-ppc4xx repository.
Jeff, one comment to your patches:
- Could you please send a commit text with a short description line which really fits in one line and if needed add some further text down below with a blank line as separation. And please write "Signed-off-by" next time. Here an example:
" [PATCH] ppc4xx: Fix CONFIG_SYS_CLK_FREQ definition in Sequoia config file
A '3' got cut off in the formatting of the last patch to automatically change the clock speed of the system clock on sequoia board.
Signed-off-by: Jeffrey Mann mannj@embeddedplanet.com "
Thanks.
Best regards, Stefan
