Hi,
The kernel 2.6.33 failed to mount the rootfs on the ramdisk. I enabled
the ramdisk block device support and ext2 filesystem as shown below.
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=16
CONFIG_BLK_DEV_RAM_SIZE=4096
CONFIG_EXT2_FS=y
Are these adequate configurations for kernel to support r

Commit 0fe1ac48 ("powerpc/perf_event: Fix oops due to

in timer_interrupt() down so that it was after the irq_enter() call.
Unfortunately this moved it after the code that checks whether it

The POWER architecture does not require stcx to check that it is operating
on the same address as the larx. This means it is possible for an
an exception handler to execute a larx, get a reservation, decide
not to do the stcx and then return back with an active reservation. If the

Hi,
I want to access the GPIO registers present in MPC8377ERDB board. I have to
write a GPIO driver for that, I am completely confused that how to do it.
Please suggest some way or doc to start with.
For the start-up, I was thinking of setting GPIO pins 9, 10 and 11 present
on the board to active

Change ACMD12 to AUTO_CMD12 to reduce the confusion.
ACMD12 might be confused with MMC/SD App CMD 12 (CMD55+CMD12 combo).
