2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

2016-04-04arm: mvebu: Add basic support for the Marvell Armada 375 SoCStefan Roese
This patch adds basic support for the Armada 375. Please note that currently the SerDes and DDR3 init code for the A375 is not included / enabled. This will be done in a later, follow-up patch. Right now, this A375 mainline U-Boot can only be used by chainloading it via the original Marvell U-Boot. This can be done via this command: => tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000 Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2016-01-14arm: mvebu: Add runtime detection of UART (xmodem) boot-modeStefan Roese
This patch adds runtime detection of the Marvell UART boot-mode (xmodem protocol). If this boot-mode is detected, SPL will return to the BootROM to continue the UART booting. With this patch its now possible, to generate a U-Boot image that can be booted either from the strapped boot-device (e.g. SPI NOR, MMC, etc) or via the xmodem protocol from the UART. In the UART case, the kwboot tool will dynamically insert the UART boot-device type into the image. And also patch the load address in the header, so that the mkimage header will be skipped (as its not expected by the Marvell BootROM). This simplifies the development for Armada XP / 38x based boards. As no special images need to be generated by selecting the MVEBU_BOOTROM_UARTBOOT Kconfig option. Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any more, its now completely removed.

2016-01-14arm: mvebu: Don't call arch_cpu_init() from SPL at allStefan Roese
This patch removes the call to arch_cpu_init() in the SPL U-Boot version. As SPL does not need all the configuration done in this function. And also does not need the reconfiguration of the internal register address to 0xf1000000. This will be done by the main U-Boot later on. This also fixes a problem with the timer not beeing initialized on AXP, as needed for the mdelay in the setup_usb_phys(). This will now only be called once in main U-Boot.

2016-01-14arm: mvebu: Add DM and OF_CONTROL support to SPLStefan Roese
This patch adds full DM support to the SPL on MVEBU. Currently only serial is supported. Other drivers will follow. This patch also adds the necessary config values for the DEBUG UART to the MVEBU defconfig files. This came in handy while implementing this DM support. Additionally, the mvebu specific SPL linker script is removed and this common one is used instead: arch/arm/cpu/u-boot-spl.lds This common linker script already handles all special cases. No need to reinvent the wheel for MVEBU here.

2015-10-21arm: mvebu: Add DM (driver model) supportStefan Roese
This patch adds driver model support for some Marvell MVEBU SoC's. Including Armada XP and 38x. All 3 currently mainlined boards are converted. DM is now selected automatically for MVEBU platforms. With this DM support now available for MVEBU, hardcoding the base addresses and other information is not necessary any more. Probing should be done by using the values provided via the device tree now instead. For this the driver also need to be converted to DM. Patches for some of the drivers will follow.

2015-10-21arm: mvebu: Do not call board_init_r() from board_init_f()Stefan Roese
Instead of calling board_init_r() directly from board_init_f(), just return from board_init_f(). This will make the code continue executing in crt0.S _main(), from which the board_init_r() is called. This patch aligns the MVEBU SPL with the correct SPL design as well as reduces the stack utilisation slightly.

2015-10-21arm: mvebu: Add option to use UART xmodem protocol via kwbootStefan Roese
This patch enables the use of the kwboot tool, to boot mainline U-Boot on the Marvell Armada XP/38x SoC's. This is done by returning to the SoC's BootROM after SPL has initialized the SDRAM. We need to make sure to not reconfigure the internal register space and MBARs. Otherwise the BootROM will not be able to continue after SPL jumps back to it. To use this feature, please don't forget to change the BOOT_FROM line in your board specfic kwbimage.cfg file this way: BOOT_FROM uart Tested on these Marvell eval boards: DB-MV784MP-GP - Armada XP DB-88F6820-GP - Armada 38x Signed-off-by: Stefan Roese <sr@denx.de> Cc: Dirk Eibach <eibach@gdsys.de> Cc: Kevin Smith <kevin.smith@elecsyscorp.com> Cc: Luka Perkov <luka.perkov@sartura.hr>
2015-07-24arm: mvebu: Add SPL SDIO/MMC boot supportStefan Roese
This patch adds basic SDIO/MMC booting support to MVEBU SoC's. Since I don't know of a way to test the boot-device upon runtime, this patch hardcodes the spl_boot_device instead. Tested on Marvell DB-88F6820-GP board. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Dirk Eibach <eibach@gdsys.de>
2015-07-23arm: mvebu: spl.c: Add call to board_early_init_f()Stefan Roese
Pin muxing needs to be done before UART output, since on A38x the UART pins need some re-muxing for output to work. Signed-off-by: Stefan Roese <sr@denx.de>
2015-07-23arm: mvebu: Call timer_init early before PHY and DDR initStefan Roese
Without calling timer_init(), the xdelay() functions return immediately. We need to call timer_init() early, so that these functions work and the PHY and DDR init code works correctly.

2015-05-05arm: armada-xp: Move SoC sources to mach-mvebuStefan Roese
Move arch/arm/cpu/armv7armada-xp/* -> arch/arm/mach-mvebu/* Since this platform will be extended to support other Marvell SoC's as well, lets rename it directly to mvebu. This will be used by the upcoming Armada 38x suport (A38x).
