2017-04-05board_f: Drop setup_dram_config() wrapperSimon Glass
By making dram_init_banksize() return an error code we can drop the wrapper. Adjust this and clean up all implementations. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2017-04-05i2c: Drop CONFIG_SOFT_I2C_MULTI_BUSSimon Glass
This is not used by any board. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org> Clean up board_f sequence a little This series tries to remove #ifdefs from the board_f init sequence. It gets as far as I2C and then we need to discuss whether we can start to remove the old I2C framework. I think that ideally each entry in the init sequence should be enabled by at most one CONFIG, which is in Kconfig and is not arch-specific.

For snow when chainloading u-boot the CPU seems to be running at full speed. The lower CPU voltage seems to be ok for u-boot, but when booting linux (bringing up all cores) I'm seeing random crashes. Bump the voltage up to a level that's safe for all cpu frequencies.

2015-11-02exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.Przemyslaw Marczak
This commit adds additional file with implementation of board detection code for Odroid-XU3/XU4. The detection depends on compatible found in fdt: - "samsung,exynos5" - uses Exynos5 generic code - "samsung,odroidxu3" - try detect XU3 revision There are few revisions of Odroid XU3/XU4, each can be detected by checking the value of channel 9 of built-in ADC: Rev ADC Board 0.1 0 XU3 0.1 0.2 372 XU3 0.2 | XU3L - no DISPLAYPORT 0.3 1280 XU4 0.1 The detection code depends on the ADC+10% value. Implementation of functions: - set_board_type() - read ADC and set type - get_board_rev() - returns board revision: 1..3 - get_board_type() - returns board type string Additional functions with return values of bool: - board_is_generic() - true if found compatible "samsung,exynos5" but not "samsung,odroidxu3" - board_is_odroidxu3() - true if found compatible "samsung,odroidxu3" and one of XU3 revision. - board_is_odroidxu4() - true if found compatible "samsung,odroidxu3" and XU4 revision. After I2C controller init, the get_board_type() can check if the XU3 board is a "Lite" variant, by probing chip 0x40 on I2C0 (INA231 - exists only on non-lite). This is useful for setting fdt file name at misc_init_r().
