[U-Boot] Using U-boot on the IXP432
by David Milway 02 May '09

02 May '09

Hi, I have been using a board with and IXP432 for about a year now, starting with Redboot but running in big endian mode. I am now looking at using u-boot for network booting but I would like to run it in little endian mode. Before I get stuck into to porting the code I have a few questions. 1) Has anybody else ported the code to the IXP432? 2) Is there any reason that the IXP cpu configuration sets the bigendian flag and should it be possible just to set it to little endian and will the bulk of the code work without modification? Thanks Dave

[U-Boot] [PATCH 0/6] eSDHC/DR USB switching on MPC837X boards
by Anton Vorontsov 02 May '09

02 May '09

Hi all, Because of pin multiplexing the eSDHC and DR USB are mutually exclusive on MPC837X processors, so we have to support switching between the two devices, and properly fixup the device tree. Patches on the way... -- Anton Vorontsov email: cbouatmailru(a)gmail.com irc://irc.freenode.net/bd2

Hi everybody... v2009.06-rc1 has just been released. Please help testing, and submit fixes to the remaining problems. Things still missing should be submitted ASAP. I would like to have a -rc2 by the end of next week, and strictly only bug fixes after this. v2009.06-rc1 will also be the base for the "next" branch which I will create soon. Please use the "next" branch as base for any new work. Note: Please keep in mind that it will be rebased against master every now and then without warning.
