* arm: armlinux: get the architecture before shutdown bareboxJean-Christophe PLAGNIOL-VILLARD2012-09-121-2/+1

* booting: more flexible Linux bootargs generationSascha Hauer2012-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | We currently use the environment variable 'bootargs' to get the Linux bootargs. This patch allows for a more flexible bootargs generation using global variables. With it the Linux bootargs are concatenated from multiple variables. This allows to replace parts of the bootargs string without having to reconstruct it completely. With this bootargs can be constructed like: global linux.bootargs.base="console=ttyS0,115200" global linux.bootargs.ip="ip=dhcp" global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)" This will then automatically be combined into a kernel bootargs string during boot. If the 'linux.bootargs.' variables are all empty the old standard 'bootargs' way will be used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Allow to compile in thumb-2 modeSascha Hauer2012-03-061-1/+16
| | | | | | | | | This shrinks the resulting binary size by ~25%. Exceptions are still handled in arm mode, so we have to explicitely put .arm directives into the exception code. Thumb-2 mode has been tested on i.MX51 Babbage board. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Fix oftree bootingSascha Hauer2012-02-131-0/+1
| | | | | | | We forgot to initialize params to the oftree to actually boot a kernel with devicetree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: call start_linux directly with initrd start/size and oftreeSascha Hauer2011-12-151-10/+10

* armlinux: cleanup linux varsSascha Hauer2011-11-291-27/+65
| | | | | | | | | | | | arch_number is currently exported to the environment but not read back on boot time which is rather confusing. system_rev and system_serial are not exported to the environment but can be set in board specific code. This patch exports all these variables to the environment and reads them back on boot time. All variables get a armlinux_ prefix, so the arch_number environment variable gets renamed.

* ARM Linux: Add device tree supportSascha Hauer2011-10-191-3/+12

|/ | | | | | | | | | | We want to use the memory banks later in the MMU which is independent of Linux, so move this to a location which is always compiled. Also, make the memory bank list global and add an iterator for it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | values into kconfig which are not user configurable at all only encourages people to put even more stuff in there. This is not good because people tend to have board patches lying around and these patches won't apply regularly if they all change the same file (arch/arm/Kconfig) Instead, introduce a function armlinux_set_architecture() which everyone can call during board setup. Similarly introduce armlinux_set_bootparams() for the boot parameter pointer.
