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(). Enabled configs: - CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG - CONFIG_ODROID_REV_AIN - CONFIG_REVISION_TAG - CONFIG_BOARD_TYPES Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Simon Glass <sjg@chromium.org> Tested-by: Anand Moon <linux.amoon@gmail.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
2015-02-25dfu: samsung: move call to set_dfu_alt_info() to dfu common codePrzemyslaw Marczak
This common call can be used for setting proper entities based on dfu command arguments. The config: CONFIG_SET_DFU_ALT_INFO, was used only for few configs, and now it is common. The board file should implement: - set_dfu_alt_info() function Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [Test HW: Odroid U3 (Exynos 4412)]
2014-09-05samsung: board: enable support of multiple board typesPrzemyslaw Marczak
This change adds declaration of functions: - set_board_type() - called at board_early_init_f() - get_board_type() - called at checkboard() For supporting multiple board types in a one config - it is welcome to display the current board model. This is what get_board_type() should return. Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
2014-09-05samsung: misc: add function for setting $dfu_alt_infoPrzemyslaw Marczak
This change introduces new common function: - set_dfu_alt_info() - put dfu system and bootloader setting into $dfu_alt_info. functions declaration: - char *get_dfu_alt_system(void) - char *get_dfu_alt_boot(void) - void set_dfu_alt_info(void) and new config: - CONFIG_SET_DFU_ALT_INFO This function can be used for auto setting dfu configuration on boot. Such feature is useful for multi board support by one u-boot binary. Each board should define two functions: - get_dfu_alt_system() - get_dfu_alt_boot() Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

2014-02-07board:samsung:common: set envs with board unified informationPiotr Wilczek
This patch sets envs that describe board information. The following envs are set: soc_id, soc_rev, board_rev. Based on this information, if CONFIG_OF_LIBFDT is enabled, the 'fdtfile' env is set as: fdtfile=${soc_family}${soc_id}-${board}.dtb The generated envs are intenionally not saved to persistent storage.
