Hi, This is regarding board with multiple variations using an upcoming SoC from TI. Variation of the board is detected by reading EEPROM using I2C after init_machine gets invoked. In one of the variation UART# used is different. Because of this decompressor logs (and early prints) can't be captured for the board variant using this different UART#. Our solution for this problem is to use different mach-id for the board using different UART#. But this solution seems to be overkill as only to capture decompressor logs, we have to use a new machine id.
As I2C will not work at the decompressor stage, I2C can't be used to detect the board type. As far as I know, ATAG is not parsed in decompressor stage and so ATAG cannot be used to determine board variant or UART#. Otherwise we will have to add capability in decompressor to parse ATAG, detect console to be used, and modify uncompress.h to select proper console for capturing decompressor logs. This seems a bad solution. Our bootloader has the capability to detect the board variant. So the best solution for us so far seems to add a new machine id, if any better solutions are possible, please let us know.
