You should not try to add this function as is to U-Boot. Instead, add the incomation contained in it (like initial values for special registers, UPM tables and RAM init sequence) to your new board config file (include/configs/viper.h) resp. your new board dependend C code (board/viper/viper.c).

[U-Boot-Users] CVS Write Access to Das U-Boot
by Marius Groeger 04 Nov '02

Dear Wolfgang, As the maintainer of the ARMboot project I welcome your effort to merge the PPCboot and ARMboot sources and making them available within the U-Boot project. Here at SYSGO, we are ready to discontinue the ARMboot project in favour of U-Boot, if we can continue our work on the U-Boot source tree. Therefore I would appreciate to have CVS write access to the U-Boot's source repository on SF.NET. Efficient Open Source development requires working along the "Release Early, Release Often" scheme. This is severely hampered if all updates are channelled through one person, who might not always be available. With the software already growing faster than we all ever thought possible, it only makes sense to split responsibilities. For that reason, we would like to keep our attention on the ARM portions on the tree. Obviously, changes in the common code must be discussed first with the maintainers, better yet, with the community. Also, to be honest, it appears a bit rude to me to take our ARMboot sources, and then just cut us off. It seems only natural to me that we both continue doing what we have done all along, only with more benefit for all of us. Please let's keep this an _open_ project, not one where only one member has the power.

[U-Boot-Users] Welcome notice

Hi Everybody, nice to meet you (again) on this list! This is just to let you know that "Das U-Boot" is on target for the first release. A working version is available on the CVS server - basicly it's identical to PPCBoot-2.0.0 which it is based on, with a globale renaming and some (minor) cleanup added. Also, the first patches have been merged. Please note: The "official" name of this project is "Das U-Boot". The spelling "U-Boot" shall be used in all written text (documentation, comments in source files etc.). Example: This is the README file for the U-Boot project. File names etc. shall be based on the string "u-boot". Examples: include/asm-ppc/u-boot.h #include <asm/u-boot.h> Variable names, preprocessor constants etc. shall be either based on the string "u_boot" or on "U_BOOT". Example: U_BOOT_VERSION u_boot_logo IH_OS_U_BOOT u_boot_hush_start For patches and contributions please see the hints in the README file.
