Well, as I understood from Russell, the main purpose of this "cut down" is to make "du -s linux/arch/arm" smaller, because there is no real need in all those boards listed in mach-types.h unless there is a support for them in mainline Linux kernel. Nevertheless the real ARM registry remains untouched - meaning that all board ids remain the same and no board is removed from the registry. This is the place where U-Boot board support diverges from Linux... Are we obliged to follow the Linux mach-types.h? Can't we just adopt Russell's "cut down" script to boards supported by U-Boot? Or will it harden the mach-types.h future updates? Have you thought of getting rid of mach-types.h completely? Making every board define its ARM registry id can work and will eliminate the need for mach-types.h update every couple of months. > I have a patch and it is the branch below > > http://git.denx.de/?p=u-boot/u-boot-ti.git;a=shortlog;h=refs/heads/update-mach-types Have you checked that none of the removed boards are in U-Boot tree? Because if there are some, then their build will be broken... And have to be fixed by... say a #define MACH_TYPE_* <id> in a board_config file. > > Please review and if it is acceptable to everyone then we should apply this > patch to remain in sync with the mainline kernel.
