I don't think so. As the comment in "/usr/include/libgen.h" suggests, we should use "the weird XPG version of this function" only when really needed. And we definitely don;t need to do that on GNU/Linux systems.

Well here are my thoughts... To enable the dcache on ARM we need an MMU page table. The position of this table is calculated in board_init_f() and it is set up by the dcache_enable in board_init_r(). The stack and caches are only related in the sense that they both need DRAM to be ready. So in principle I don't see any reason why we cannot enable the dcache during board_init_f(). What I suggested is that we tackle this once the generic board series goes in. I am happy to do this work. That way we only need to do one framework and all the archs can use it.

[U-Boot] Integity validation (checksum) of a squashfs root file system
by Pascal Levesque 03 Mar '12

03 Mar '12

Hi, I would like to validate the integrity (checksum) of a squashfs root file system before starting Linux. Current strategy I am using is: - Wrap squashfs rootfs inside a u-boot image - TFTP download on the target - Download validation using iminfo - Save squashfs rootfs in flash without the image header (Linux failed to load squashfs rootfs if u-boot image is present) Problems: - I need to hardcode squashfs rootfs offset in u-boot image in order to be able to flash it - U-Boot image header information (size, crc, ...) is lost after a reboot. It is not possible to check the integrity of the flash content. I would like to save some fields of u-boot image header (size, crc, ...) in u-boot environment variables. And then do an integrity check at boot time. I have not find a way to extract those fields and save them without changing u-boot code. I have added some code to “iminfo” command to set environment variables for CRC, size, payload offset, timestamp. Is it an acceptable way of doing it? Is there a better way of doing it? Thanks in advance, Pascal

[U-Boot] Request for help: Regarding u-boot on Pandaboard ES
by jagan 03 Mar '12

03 Mar '12

Hi, I have clone the new master branch from git://git.denx.de/u-boot.git And I have seen few changes w.r.t to Panada ES. I compiled as per the procedure. But when I copy MLO, u-boot.bin, u-boot.img on to BOOT partition. I wasn't see any prompt or nothing has in on minicom port. Could you please send any suggestion or pointers. is that still need a few more patches. Regards, Jagan.
