This feature requires some platform configuration data in the environment, which is: -${platname}_setup_N_name - name of this setup -${platname}_setup_N_partitions - GPT partitions or NULL if MBR -${platname}_setup_N_alt_system - dfu_alt_info with system entities -${platname}_setup_N_bootpart - boot partition number for this setup -${platname}_setup_N_rootpart - root partition number for this setup And for at least one setup it requires: -${platname}_setup_cnt - number of ${platname} configs -${platname}_setup_chosen - chosen plaform config -${platname}_setup_active - active platform config (autoset) Two environment variables are used to switch/check active setup: -${platname}_setup_chosen - can be changed manually -${platname}_setup_active - should be the same as chosen If chosen setup is not set, then will be automatically set on boot by setting proper env: - $partitions := ${platname}_setup_N_partitions - $dfu_alt_system_${platname} := ${platname}_setup_N_alt_system - $mmcbootpart := ${platname}_setup_N_bootpart - $mmcrootpart := ${platname}_setup_N_rootpart - ${platname}_setup_active := ${platname}_setup_chosen If ${partitions} are: - set, then gpt write is called - unset, e.g. when using MBR - then partition table is unchanged Config: - CONFIG_PLATFORM_SETUP Change-Id: Ib9f90415b92ec1d67a9bf6b84e7ab5d5deea8a7d Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com>

This patch introduce some cleanup in set_board_info(), related to the listed code changes: Change 1: The name of function get_board_type() was unclear, so now it is changed to get_board_model(). Change 2: The previous version of get_board_name() was returning the platform name - now it returns full boardname. Change 3: Add new function get_plat_name() - returns platform name. This is useful for platform common usage like environment settings. Change 4: Update odroid.c by change get_board_type() to get_board_model().

2015-05-18samsung:board: dram_init(): alloc memory to store fdt dram infoPrzemyslaw Marczak1-15/+15
For CONFIG_OF_MULTI the dram_init() function gets memory information from the device tree blob by the call to fdtdec_decode_memory(). The same is done second time in dram_init_banksize() - this was the simplest because board info structure is not initialized at dram_init() stage. This change uses malloc and gd->priv pointer to store the memory banks parameters and next uses it in dram_init_banksize(). Thanks to this change, the boot time decreases, because, the function fdtdec_decode_memory() is called only once.

2015-05-18trats2: add support to interactive chargerPrzemyslaw Marczak2-18/+307
This commit adds support to interactive charger api which means an implementation of listed functions: - charger_enable() - enable the charger.Charger can be enabled automatically if the device power on state is triggered by USB cable connection. - charger_type() - this function returns device type connected to usb port of device. For charger api matters only positive value. - battery_present() - check if battery is connected (DETBAT pin) - battery_state() - check battery charge level. Returns percent value. - low_power_mode() - switch SOC into low power mode which covers: - disable cores: 1, 2, 3, - disable SOC unused power domains, - decrease CPU clock to 200 MHz After low_power_mode() function call, device should be restarted, which is implemented in interactive charger.

Usage: - battery [<state>] [<charge>] Option "state" will display battery screen for 2 seconds. Option "charge" will start interactive charger mode. Interactive charger mode can be stopped by: - pressing CTRL+C keys combination, or device reset by: - pressing PWR key for 5 seconds (only if SOC > 20% - one grey bar), - pressing PWR key for 10 seconds, which is PMIC reset.

This patch adds checking the special signature of downloaded U-Boot binary. The new function check_board_signature() is called before do dfu_write() in thor gadged code. The board signature is checked for: - the running U-Boot - downloaded 'u-boot-mmc.bin' at offset of binary start defined by: - (CONFIG_SIGN_IMAGE_SIZE - HDR_SIZE) The download can succeed when signatures are equal. The default U-Boot image size defined by CONFIG_SIGN_IMAGE_SIZE is 1MB. Other changes: - print info about running/downloading U-Boot signature - print info about wrong image signature/size - don't allow downloading unsigned or signed wrong U-Boot image - allow download any image if no signature found at running U-Boot The first version added by: Signed-off-by: Inha Song <ideal.song@samsung.com> Upgrade: Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com>

2015-05-10overo: Fix regression introduced in a6b541bArun Bharadwaj1-14/+0
U-Boot has been broken on Overo boards since commit a6b541b09022acb6f7c2754100ae26bd44eed1d9. This is because the gd pointer is not set early enough anymore, such that the i2c_set_bus_num in get_board_revision can safely execute. This results in a console hang at SPL and the boot does not proceed. This piece of code is anyway necessary only for really old Overo boards with revision numbers <= 2410 and not required for the newer boards. For these older boards, u-boot v2014.10 still works fine.

Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build in complete drm-stuff into linux kernel. In very small applications only we use the simple-framebuffer. So we have 2 use-cases: - device operating on drm-driver (let simplefb node disabled) - device operating on simplefb-driver (activate simplefb node and reserve mem) The decision is made by means of "simplefb" environment variable. simplefb = 0 we don't enable the (maybe) existing simplefb node and all the rest around display is up to the linux-kernel. We just disable the backlight, beceause we do not want see the flicker during take over of drm-driver. simplefb = 1 we enable the (maybe) existing simplefb node and reserve framebuffers size in memory.
