Hello; I just started working with the ChiliSOM module [1] -- in my particular case it is part of the Chiliboard [2]. The ChiliSOM is a nice little module based on the TI AM335x ARM SoC. I already started porting the mainline U-boot for it. The DRAM and serial console seem to work so far. I hope the rest (Ethernet, USB) won't be that painful.
When implementing the support for this SOM I copy-pasted a lot of code (almost all of it) from the ti/am335x/board.c. I had to copy the linker script and include/configs/am335x_evm.h (which has reference to the particular linkerscript) as well. Not only I know this is very wrong, I do not like it. One possibility would be to modify the ti/am335x/board.c to be able to work with this SOM, although the code reading the board identification (from serial EEPROM) at the beginning of many functions seem to be an issue. Not very elegant solution would be to #ifndef them for all the other boards with the exception of the ChiliSOM. Another possibility would be to have an extra board.c, however the include/configs/am335x_evm.h will be used as a configuration file with the CONFIG_SYS_LDSCRIPT somehow (how?) pointing to some generic am335x linker script. Is there an interest in ChiliSOM U-boot support? What is the most elegant way resulting in the least code duplication? I will appreciate your help.
