| | | | | | | | | | Use ARM_USE_COMPRESSED_DTB for all AM335x based board, to reduce the image size even more. Saves about 9kB in MLO image and 20kB in barebox image. Signed-off-by: Teresa Remmet <t.remmet@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | ARM: am335x bone: Fix Booting from eMMCSascha Hauer2015-01-061-0/+3
|/ | | | | | | | | | | | | | | | | Booting a beaglebone black from eMMC is broken since: commit 0d6392de4ad824a6553c0e3e3e18edef689a7c85 Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Thu Jun 5 12:09:07 2014 +0200 ARM: AM335x: Beaglebone: Use stripped down devicetree for MLO The stripped down device tree does not have the eMMC device node which the beaglebone black needs for booting. Add this node to the common dts file, but keep it disabled. It gets enabled later with a call to am33xx_of_register_bootdevice() when the system is booted from eMMC.

* ARM: AM335x: Beaglebone: Fix memory setup for Beaglebone blackPhilipp Zabel2014-06-171-0/+17
| | | | | | | | | | | | | | | | Commit 0d6392de4ad824a6553c0e3e3e18edef689a7c85 introduced a stripped down device tree used for both white and black Beaglebone variants that included the 256 MiB memory node from am335x-bone-common.dtsi. This leads to the following error in the MLO: mmu: Critical Error: Can't request SDRAM region for ttb at 9fff4000 This patch removes the (for the Beaglebone black) invalid memory size from the common device tree and instead registers the memory bank manually in the board file.

* ARM: AM335x: Beaglebone: Use stripped down devicetree for MLOSascha Hauer2014-06-051-5/+5
| | | | | | | | | The beaglebone white and black have different devicetrees. Both get linked into the MLO which makes it too big. Use a devicetree generated from am335x-bone-common.dtsi which both board variants can share. This reduces the binary size by about 30k. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM: omap: fix omap_save_bootinfoSascha Hauer2013-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | omap_save_bootinfo derefences the argument passed to barebox without checking it for validity. This breaks 2nd stage booting where r0 is undefined. The best we can do is to check whether the pointer is somewhere in SRAM and is word aligned. This at least makes sure that we do not oops. This introduces SoC specific xxx_save_bootinfo variants since the SRAM addresses/sizes differ between SoCs. Additionally fix the prototype for omap_save_bootinfo. It uses r0, so it must be passed this variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | Set model and hostname at boardlevelSascha Hauer2013-08-162-2/+3
|/ | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* arm: omap: store boot source info from ROM loaderTeresa Gámez2013-07-101-1/+4
| | | | | | | | | | | | | | | | | | The ROM loader passes the address of a buffer to the MLO in register 0. Store this data so we can find the boot source later. On the same way the bootinformation are passed to the barebox, then. It has to be enshured that r0 contains always the buffer or the boot source detection will not work. Applied this on all OMAPs. This patch is based on work of Jan Luebbe <jlu@pengutronix.de>. Compile tested on all OMAP boards. Tested on pcm049, phyCARD-A-L1 and pcm051.
