The PWM pins on North Bridge on Armada 37xx can be configured into PWM or GPIO functions. When in PWM function, each pin can also be configured to drive low on 0 and tri-state on 1 (LED mode). The current definitions handle this by declaring two pin groups for each pin: - group "pwmN" with functions "pwm" and "gpio" - group "ledN_od" ("od" for open drain) with functions "led" and "gpio" This is semantically incorrect. The correct definition for each pin should be one group with three functions: "pwm", "led" and "gpio". Change the "pwmN" groups to support "led" function. Remove "ledN_od" groups. This cannot break backwards compatibility with older device trees: no device tree uses it since there is no PWM driver for this SOC yet. Also "ledN_od" groups are not even documented.

The gdsys a38x config file (controlcenterdc_defconfig) uses BootROM to load U-Boot proper. Since it is now possible to do this via U-Boot SPL framework, we do not need to provide custom spl_board_init() which calls return_to_bootrom(). Signed-off-by:

Macro CONFIG_SYS_U_BOOT_OFFS is set but not used anymore. Remove it. Signed-off-by:
-
This padding depends on board config file and therefore it makes the mkimage binary tool board specific, which is not correct. One cannot use mkimage tool built as a result for board A to generate images for board B, even if both A and B are on the same platform. This CONFIG_SYS_U_BOOT_OFFS padding was needed when kwbimage v1 contained SPL code which loaded U-Boot proper based on CONFIG_SYS_U_BOOT_OFFS, instead of reading correct offset from kwbimage header. Now that SPL code parses kwbimage header and deterinate correct offset, there is no need for this CONFIG_SYS_U_BOOT_OFFS padding anymore. By removing it we also reduce the size of SPL code and therefore also decrease the final size of v1 kwbimage. This means there is more space for U-Boot proper binary. Signed-off-by:

The SPL code now already parses kwbimage v1 headers where all necessary information about how to load and execute U-Boot proper is present. The legacy 64-byte U-Boot header is not used anymore. Remove this 64-byte header by putting u-boot.bin binary (instead of u-boot.img) into kwbimage v1 and let SPL code or BootROM to load U-Boot directly at its execution address. Signed-off-by:
-
Now that proper load and execution addresses are set in v1 kwbimage we can use it for loading and booting U-Boot proper. Use the new spl_parse_board_header() function to implement parsing the kwbimage v1 header. Use information from this header to locate offset and size of the U-Boot proper binary, instead of using the legacy U-Boot header which is prepended to the U-Boot proper binary stored at fixed offset. This has the advantage that we do not need to relay on legacy U-Boot header anymore and therefore U-Boot proper binary can be stored at any offset, as is the case when loading & booting U-Boot proper by BootROM. The CONFIG_SYS_U_BOOT_OFFS option is therefore not used by SPL code anymore. Also allow to compile U-Boot SPL without CONFIG_SPL_SPI_FLASH_SUPPORT, CONFIG_SPL_MMC_SUPPORT or CONFIG_SPL_SATA_SUPPORT set. In this case BootROM is used for loading and executing U-Boot proper. This reduces the size of U-Boot's SPL image. By default these config options are enabled and so BootROM loading is not used. In some cases BootROM reads from SPI NOR at lower speed than U-Boot SPL. So people can decide whether they want to have smaller SPL binary at the cost of slower boot. Therefore dependency on CONFIG_SPL_DM_SPI, CONFIG_SPL_SPI_FLASH_SUPPORT, CONFIG_SPL_SPI_LOAD, CONFIG_SPL_SPI_SUPPORT, CONFIG_SPL_DM_GPIO, CONFIG_SPL_DM_MMC, CONFIG_SPL_GPIO_SUPPORT, CONFIG_SPL_LIBDISK_SUPPORT, CONFIG_SPL_MMC_SUPPORT, CONFIG_SPL_SATA_SUPPORT and CONFIG_SPL_LIBDISK_SUPPORT is changed from strict to related "imply" (which can be selectivelly turned off and causes booting via BootROM). Options CONFIG_SYS_SPI_U_BOOT_OFFS, CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR and CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET have to to be set to zero as they define the location where kwbimage header starts. It is the location where BootROM expects start of the kwbimage from which it reads, parses and executes SPL part. The same applies to option CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR, which has to be set to one. Update all config files to set correct values of these options and set CONFIG_SYS_U_BOOT_OFFS to the correct value - the offset where U-Boot proper starts. Signed-off-by:

Platform specific BootROM may use its own image type for loading SPL or U-Boot proper. In some cases it makes sense to not use BootROM supplied code for booting U-Boot proper but rather to use U-Boot SPL for this, e.g. when U-Boot SPL can load U-Boot proper faster than BootROM. In this case it is required for platform board code to parse and load U-Boot in BootROM specific image type. This change adds support for parsing platform / board / BootROM specific image types via weak function spl_parse_board_header() which is called before marking boot image as a raw. Signed-off-by:
-
Some image types (e.g. kwbimage v1) store the offset to SPL binary and offset to U-Boot proper binary in their headers. To avoid reading SPL binary when loading U-Boot proper, add support for specifying offset in struct spl_image_info, which defines the offset from the beginning of the header and the beginning of the executable data. Initial support is added only for SPI, MMC and SATA code. We can extend it later if needed. Signed-off-by:

Current code uses hack in board_init_f() which calls return_to_bootrom() to skip U-Boot SPL code and return back to BootROM to load U-Boot via UART or from NAND. This change migrates that hack from the board_init_f() function and changes it to return BOOT_DEVICE_BOOTROM instead of returning to BootROM directly, so that U-Boot's SPL framework is used for returning to BootROM.

The data part of v1 kwbimage currently contains U-Boot binary prepended by 64 bytes long Legacy U-Boot image header. This means that the load address is currently substracted by 64 bytes to ensure that U-Boot's entry point is at specified execution address. As mkimage has already separate arguments for load (-a) and execution (-e) address, there is no need to derive fixed load address from execution address. Therefore remove this load address hack from the kwbimage tool and support generating v1 kwbimage with arbitrary addresses for load and execution. Finally, calculate correct load address by caller for mkimage tool in Makefile. File u-boot-spl.kwb is always a v1 kwbimage and it is the only v1 kwbimage which U-Boot's build system generates.
