* arm: mvebu: Add runtime detection of UART (xmodem) boot-modeStefan Roese2016-01-14-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* arm: mvebu: Add option to use UART xmodem protocol via kwbootStefan Roese2015-10-21-0/+16
| | | | | | | | | | | | | | | | | | | | | | 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>
* arm: armada-xp: Move SoC sources to mach-mvebuStefan Roese2015-05-05-0/+61
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).
