[U-Boot] Regression due to: arm: Add Prep subcommand support to bootm
I just tried the latest u-boot/master, at commit:
3f0675d Merge branch 'marek.vasut@gmail.com' of git://git.denx.de/u-boot-staging
This fails to boot a Linux kernel on my ARM Tegra board; the boot log is:
==================== ## Booting kernel from Legacy Image at 00408000 ... Image Name: Linux-3.4.0-rc1-next-20120405-00 Image Type: ARM Linux Kernel Image (no loading done) (uncompressed) Data Size: 2756424 Bytes = 2.6 MiB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK ## Flattened Device Tree blob at 01000000 Booting using the fdt blob at 0x01000000 XIP Kernel Image (no loading done) ... OK OK Loading Device Tree to 010fa000, end 010ff726 ... OK
Starting kernel ...
Uncompressing Linux... done, booting the kernel. Warning: Neither atags nor dtb found ====================
If I revert commit 0a672d4 "arm: Add Prep subcommand support to bootm", then everything works fine again.

I don't see this on beagleboard so we'll need some more tracking down of just how this broke tegra from you :( Thanks!

This only seems to affect booting with a device tree. Booting without passing a device tree works fine.
I also tested "mkimage -T kernel_noload" (which I typically use) vs. "mkimage -T kernel", and it makes no difference to either DT or non-DT boots, so that's one potentially unusual thing I do eliminated.
