[U-Boot-Users] added dcache_disable(), dcache_status() stubs to ARM920T with no MMU support
by Olexiy Avramchenko 22 Feb '07

22 Feb '07

Hello, list I'm using U-Boot for ARM920T target to load ELF image on board. ELF loader ("common/cmd_elf.c") requires dcache_status() and dcache_disable() regardless of whether MMU is used or not. I added two stubs in "cpu/arm920t/cpu.c" for the case when MMU is not used, but different CPUs may also be affected by this. Best regards, Olexiy

Re: [U-Boot-Users] [PATCH] Fix relocation problem with "new"get_dev() function

Hi Grant, I don´t know if your approach is a better solution if your final intention is to clean up the code from the C files of U-Boot where the relocation is done manually. I think this would be the final goal, so, if the BROKEN or FIXED defines are provisional and only for test proposes I think both are equally valid. Regards, Txema. -----Mensaje original----- De: u-boot-users-bounces(a)lists.sourceforge.net [mailto:u-boot-users-bounces@lists.sourceforge.net] En nombre de Grant Likely Enviado el: miércoles, 21 de febrero de 2007 18:01 Para: Stefan Roese CC: U-Boot-Users Asunto: Re: [U-Boot-Users] [PATCH] Fix relocation problem with "new"get_dev() function At first glance this looks like a bad idea because it means every board config file must be touched; but every config file needs to be touched regardless. Either: a) touch every config file now (by adding the "IT'S BROKEN" define; or b) touch every config file later (by removing the "IT'S FIXED" define when all board ports are working and the hooks are no longer needed).

Hi, This is Mushtaq khan, working as a Design engineer in a company called Processor Systems (India) Pvt. Ltd. I have added a support for SATA in both legacy and native mode for Intel processor with ICH-5 in u-boot. I don't know the procedure to submit the code.Please some one let me know the procedure to submit the code to the u-boot organization. Thanks, Mushtaq Khan.

[U-Boot-Users] [PATCH] Fix relocation problem with "new" get_dev() function
by Stefan Roese 21 Feb '07

21 Feb '07

This patch enables the "new" get_dev() function for block devices introduced by Grant Likely to be used on systems that still suffer from the relocation problems (manual relocation neede because of problems with linker script). Hopefully we can resolve this relocation issue soon for all platform so we don't need this additional code anymore.
