Hi Russell & Tony,

AM335X EVM (based on AM33XX device) only supports DT boot mode and
doesn't have CONFIG_MACH_AM335XEVM option defined. Some time back during
baseport submission we had aligned that, we won't create separate EVM
options, killing the board file all-together.

Having said that, the early printk option (DEBUG_LL) is broken, the
auto-generated file "./include/generated/mach-types.h" still refers to
CONFIG_MACH_AM335XEVM option,

The way we're heading is that the DEBUG_LL options will only work for
one hardcoded machine where you need to select the uart type and address
in Kconfig. Or just patch it in.
 

#ifdef CONFIG_MACH_AM335XEVM
# ifdef machine_arch_type
#  undef machine_arch_type
#  define machine_arch_type     __machine_arch_type
# else
#  define machine_arch_type     MACH_TYPE_AM335XEVM
# endif
# define machine_is_am335xevm() (machine_arch_type == MACH_TYPE_AM335XEVM)
#else
# define machine_is_am335xevm() (0)
#endif


So I am thinking of changing the config_xxx option to SOC_AM33XX or
ARCH_OMAP2PLUS, something like below,

am335xevm        SOC_AM33XX          AM335XEVM         3589

OR

am335xevm        ARCH_OMAP2PLUS      AM335XEVM         3589


Can you comment on this? Based on that I will submit the patch.

I think that would at minimum break things for autogenerated
mach-types.h where if only some other non-am335xevm machine is
selected (like omap-generic) things don't get optimized out any
longer as they currently do.

Regards,

Tony
