The ti816x/am389x SoC is the first generation in what U-Boot calls the "am33xx" family. In the first generation of this family the DDR initialization sequence is quite different from all of the subsequent generations. Whereas with ti814x (second generation) we can easily work the minor differenced between that and am33xx (third generation), our attempts to do this for ti816x weren't sufficient. Rather than add a large amount of #ifdef logic to make this different sequence work we add a new file, ti816x_emif4.c to handle the various required undocumented register writes and sequence and leverage what we can from arch/arm/mach-omap2/am33xx/ddr.c still. As DDR2 has similar problems today but I am unable to test it, we drop the DDR2 defines from the code rather than imply that it works by leaving it. We also remove a bunch of other untested code about changing the speed the DDR runs at.

Signed-off-by: Tom Rini trini@konsulko.com --- Note that today the board will boot perhaps 3 out of 5 times in a row. This allows us to perform power on reset reliably. And yes, there are lots of undocumented register writes, but no, it is unlikely that they will ever be documented. --- arch/arm/include/asm/arch-am33xx/clocks_am33xx.h | 1 + arch/arm/include/asm/arch-am33xx/ddr_defs.h | 6 + arch/arm/mach-omap2/am33xx/Makefile | 3 + arch/arm/mach-omap2/am33xx/board.c | 21 +++ arch/arm/mach-omap2/am33xx/clock_ti816x.c | 68 ++------ arch/arm/mach-omap2/am33xx/ddr.c | 9 ++ arch/arm/mach-omap2/am33xx/emif4.c | 41 +---- arch/arm/mach-omap2/am33xx/ti816x_emif4.c | 165 +++++++++++++++++++ board/ti/ti816x/evm.c | 192 +++++------------------ include/configs/ti816x_evm.h | 15 -- scripts/config_whitelist.txt | 5 - 11 files changed, 260 insertions(+), 266 deletions(-) create mode 100644 arch/arm/mach-omap2/am33xx/ti816x_emif4.c

- Switch to using <configs/ti_armv7_omap.h> and family. This lets us drop lots of custom defines. - Ensure that our default environment uses DEFAULT_LINUX_BOOT_ENV so that Linux will boot correctly. - Enable CONFIG_DISTRO_DEFAULTS - Switch to using CONFIG_OF_CONTROL - Various other cleanups to match other SoCs in the family line.

The symbol CONFIG_TI81XX is used for the parts that are common to the TI816x and TI814x SoCs and are not part of CONFIG_ARCH_OMAP2PLUS nor CONFIG_AM33XX. It however has so few uses that we can just modify the code to check for both and drop the symbol. The symbols CONFIG_TI816X and CONFIG_TI814X are for the repective SoCs.
