Is that ok? I would suggest get those 5 done, reviewed and well tested first. Otherwise, you might find yourself doing the same fix to many cpu's instead of only 5. Then do the other ones and ask maintainers (or somebody else with access to a suitable board on his desk) to perform the test. If you could provide them with a few instructions, they can do the tests real quick and you get consistent reports.

[U-Boot] AVR32 support
Dear list, A few days ago I tried to upgrade the bootloader of my AVR32 NGW100 based development platform to the latest release of U-Boot (2010.06). I use OpenWRT on it and also the U-boot provided with it. At first, it didn't even compile. Secondly, it didn't work [1]. Reading through the mailing list archives brought a solution for the first problem. The second problem was more complicated and discussed without a resolution. I'm upgrading from an ancient version 1.3.3 due to some bugs. When I used U-boot on a previous project, it had some problems doing an tftp get due to (if I recall correctly) $serverip not being retrieved correctly from the environment settings. The work around was to set it again after every reset. So I'm wondering what to do. I can try 1.3.4 or so. I already tried 2008.10, but it failed because it thinks the flash is 4 gig when the environment is empty and kept crashing (some DMA error). This also happened to 2010.06. Reverting to 1.3.3 was the only way to get my board working again. Luckily, I'm blessed with a working JTAG device. Any advice? -- Bas.

Is that the same problem that makes flash erase actions fail with the error that the start or end address does not match a sector boundary? It also includes a trivial enhancement to the exception reporting which I found very useful during debugging. Hopefully this will make mainline u-boot useful again on AVR32. Without this fix, v2008.10 is the latest usable release. I had a problem with this version as well when the environment was empty. It said the flash was 4Gig and kept crashing with some DMA error (NGW100 board). The patches are based on v2010.06, but it merges fine with the latest upstream master. The AVR32 master branch currently contains a workaround which I plan to revert if these patches are acceptable. I'm happy to test them on my board.
