* ARM: i.MX6: dts: edmqmx6: use new dts approachSilvio Fricke2014-05-081-320/+11

* ARM: tegra30: ramp vdd_core to 1,2VLucas Stach2014-05-082-0/+19
| | | | | | | | | This isn't much different from the default 1,16V and I haven't seen this make a difference on any board, but it seems to be required for some T30 SKUs. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: tegra30: slow down CPU to 600 MHzLucas Stach2014-05-081-4/+4
| | | | | | | | | | It's not safe to ramp up the CPU clock speed to 1,4 GHz on all T30 SKUs, as this may result in failure to start the kernel properly. Start CPU at 600 MHz, which is safe even for the slowest SKUs. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: phycard-imx6: fixup for barebox_arm_entry signature changeLucas Stach2014-05-071-2/+2
| | | | | | | | | This board wasn't changed properly, as it was merged in the short timeframe where the signature change waited to be applied. Change it now to get rid of the compiler warning. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: bootm: fix default uImage placementLucas Stach2014-05-051-7/+10
| | | | | | | | | | | | | For small systems we would put the zImage at 32KiB after the start of memory, and put the DT a bit after the uImage. The kernel will always try to relocate itself and overwrite the DT. Try to be more clever at uImage placement to avoid triggering the kernel relocation.

* ARM: bootm: be more clever while deciding where to put zImageLucas Stach2014-05-051-28/+29
| | | | | | | | | | | | | | For small systems we would put the zImage at 8MiB after the start of memory, and put the DT a bit after the zImage. When we encounter an image which is bigger than 8MiB uncompressed, the kernel would try to relocate itself and overwrite the DT. Try to be more clever at zImage placement to avoid triggering the kernel relocation. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: imx: move malloc area to upper memory bank by defaultLucas Stach2014-05-051-49/+66
| | | | | | | | | | If we have two discontinuous memory banks we want to move the malloc area into the upper bank by default to leave as much free space in the lower bank, where we have to place kernel, oftree and initrd.

* ARM: change signature of barebox_arm_entryLucas Stach2014-05-0587-196/+204
| | | | | | | | | | | Mostly to make it clear that boarddata needs to be something we can dereference. As this is a pretty invasive change, use the opportunity to make the signature 64bit safe. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * tegra: disable more lowlevel unsafe switch optimizationsLucas Stach2014-04-233-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | fno-jump-tables isn't enough to guard against gcc switch optimizations that are unsafe to use in code that runs before relocation. The switch-tree-conversion opt pass may generate lookup tables that are placed in the data section and accessed via absolute adressing, which fails prior to relocation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.
