[U-Boot-Users] [PATCH] m68k fix for Ethernet Buffers at address 0
by Wilson Callan 23 Jul '07

23 Jul '07

Hi, Attached is a patch file to address the problem where eth_init() is called before NetRxPackets is initialized. This results in the receive buffers being set to address 0, which overwrites the vector table when packets are received. This patch simply removes the call to eth_init() because its called again later when TFTP is needed. The u-boot methodology is to only init hardware when its going to use it. Note that this change may break some systems that relied on u- boot to set the MAC Address in all cases. Those systems are supposed to get the MAC from u-boot parameters. CHANGELOG: Fix m68k problem where eth_init() is called before NetRxPackets is initialized. Fixed by removing call to eth_init(). Signed-off-by: Wilson Callan <wcallan(a)savantav.com>

[U-Boot-Users] {PATCH] new CONFIG_IMAGE_VERIFY
by Wilson Callan 20 Jul '07

20 Jul '07

Hi, I've added an option that allows the BSP to do further verification of the image before its allowed to run. I'll show how i used it when i resubmit my BSP shortly, but this patch just contains the option. Here is the README entry: +- CONFIG_IMAGE_VERIFY + + If this option is defined, bootm will callout to + image_verify() and only boot the image if it returns nonzero. + Image_verify() should be defined by the BSP in board/ to + do whatever it wants to validate the image is okay for the + board. For example, it might want check something in the + hdr->ih_name string. CHANGELOG: Added CONFIG_IMAGE_VERIFY to allow BSP to verify image before allowing it to boot.

I'll add that to my u-boot-fdt repo. FWIIW, my original proposal (and code) was to *REMOVE* the automagic modifications of the fdt blob from the bootm command. My original proposal was to replace "bootm" in scripts (or in the user's fingers) with "fdt chosen && fdt env && fdt bd_t && bootm" (or an appropriate combination thereof). I was shouted down. ;-) IMHO, having bootm modify the fdt blob is a poor practice. Bootm's mandate is to boot an image from memory, it *shouldn't* be to rewrite the fdt blob. Unfortunately, we had an existing practice (poor, IMHO) of having bootm rewrite the fdt blob and so the current implementation was done to meet the "user expectation" of bootm "just working" without needing to add "fdt xyz" before the bootm command. gvb (wipes the foamy spit off his face)

[U-Boot-Users] [PATCH] new CONFIG_RETURN_FROM_BOOTM
by Wilson Callan 20 Jul '07

20 Jul '07

Hi, I've added an option similar to the netretry=no environment option which allows a script to control the retry operation for networking. This option controls a retry operation for bootm. Here is the README entry: +- CONFIG_RETURN_FROM_BOOTM + + Return from the bootm command instead of rebooting. This + is useful for setting up multiple boot image options in a + script. It allows the script to control the retry + operation. For example, these scripts setup a system that + will attempt a primary flash image, then a backup image + location, then resort to TFTP: + "boot_tftp=dhcp 3c0;bootm 3c0;reset\0" /* if fails, reset */ \ + "boot_flash=bootm ff050000 3c0;bootm ffc00000 3c0;run boot_tftp;reset\0" CHANGELOG: Added CONFIG_RETURN_FROM_BOOTM to control retry operation of bootm command.
