I have posted patches upstream to convert Tegra to "single zImage"; the ability for a single zImage to boot on multiple different SoCs. I expect to put them into linux-next early next week. You'll see a few changes due to this: 1) A few CPU ERRATA WORKAROUNDS are NO LONGER ENABLED by the kernel. The latest upstream U-Boot enables these before booting the kernel now. You will want to: 1a) Update your bootloader to the master branch in either u-boot-tegra.git or u-boot-arm.git, and likely soon the u-boot.git. 1b) Update your bootloader to some other bootloader that enables the workarounds. 1c) Write a small stub that the is prepended to zImage which enables the workaround. You should be able to copy the code from U-Boot or the kernel. 1d) Ignore this issue and hope you don't get bitten. The errata documentation doesn't sound like they would trigger that often. IIRC, the impact in all cases would be silent data corruption. I've actually been running a mix of bootloaders that do and don't enable the WAR and haven't noticed any issues. I should update though! 2) Minor Kconfig option layout changes. 3) No debug spew from the uncompressor. I hope to fix this very soon; most of the work has already been done by Shawn Guo @ Linaro, but I need to tweak the Tegra implementation in order to enable it. Earlyprintk still works fine though. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
