[U-Boot] [PATCH] powerpc: Fix declaration type for I/O functions
by Prabhakar Kushwaha 25 Aug '12

Prototype declaration of I/O operation functions are not correct. as both 'extern' and function definition are at same place. Chage protoype declaration as static.

[U-Boot] [PATCHv2 1/2] mpc85xx: Initial SP alignment is wrong.
by Joakim Tjernlund 23 Aug '12

23 Aug '12

PowerPC mandates SP to be 16 bytes aligned. Furthermore, a stack frame is added, pointing to the reset vector which may in the way when gdb is walking the stack because the reset vector may not accessible depending on emulator settings. Also use a temp register so gdb doesn't pick up intermediate values.

[U-Boot] dwc_ahsata vs ahci
by Pavel Herrmann 23 Aug '12

23 Aug '12

Hi, While working on the DM project, I found out that there are two implementations of AHCI drivers - one in block/ahci.c, one in block/dwc_ahsata.c what is the difference between them (apart from the obvious, ahci.c exposes SCSI API, dwc_ahsata exposes SATA API)? are there any problems that would prevent me from merging them? thanks Pavel Herrmann

[U-Boot] usb_test_unit_ready called every block read - performance
by Jim Shimer 19 Aug '12

19 Aug '12

While tuning ext2load, we found that usb_test_unit_ready was being called every block read. We compared the usb block storage to the scsi block storage cmd_scsi.c, and found that the scsi device was only calling its scsi_setup_test_unit_ready() during scsi_can. It appears that usb_test_unit_ready() really only needs to be called once during usb_stor_scan(), via usb_stor_get_info(). Is there a particular reason usb_test_unit_ready is called for every block read, or do you think its ok to only call during usb_stor_scan()? We're finding this speeds up ext2load quite a bit.
