[U-Boot] [PATCH v3] nand: Fix cache and memory inconsistent issue
by Dave Liu 17 Dec '08

17 Dec '08

we load the secondary stage u-boot image from NAND to system memory by nand_load, but we did not flush d-cache to memory, not invalidate i-cache before we jump to RAM. when the system is cache enable and the TLB/page attribute of system memory is cacheable, it will cause issue. - 83xx family is using the d-cache lock, so all of d-cache access is cache-inhibited. so you can't see the issue. - 85xx family is using d-cache, i-cache enable, partial cache lock. you will see the issue. The patch fix the cache issue. Signed-off-by: Dave Liu <daveliu(a)freescale.com> --- Stefan, I'm not familiar with ppc4xx, could you workout one patch for nand_boot.c?

[U-Boot] device-tree check MPC5200B Lite
by Marco Antônio Possamai 17 Dec '08

17 Dec '08

Greetings, I've read the FAQ in http://www.denx.de/wiki/view/DULG/LinuxHangsAfterUncompressingKernel, concerning the 'Linux hangs after uncompression' problem. And I'm not sure how to verify if the device tree I've generated (along with the image) is alright or not. I don't know where I can find the mapping of IMMR or PCI in the files present there, for instance. Is there any documentation or literature that could help me? Some specs: Board: MPC5200B Device-tree compiler version: 1.2.0 Kernel image to be passed to the board: Linux-2.6.26.8-dirty Xenomai: 2.4.x U-Boot version: 2008.10 Thanks in advance.

Dear All, As of now in the U-boot only TFTP client is supported. I am planning to have TFTP server support in the u-boot. Can you please help me in this regarding? Please provide me few links if this has been done already, or links from where i can take some information and start working on it. Hope to get some advice on this soon from you. Thanks, Santosh

[U-Boot] [PATCH v4 1/4] Introduce virt_to_phys()
by Kumar Gala 17 Dec '08

17 Dec '08

virt_to_phys() returns the physical address given a virtual. In most cases this will just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address.
