* tegra: avp_init: write DT address register earlierLucas Stach2015-03-031-3/+3
| | | | | | | | | Otherwise the write would be skipped if we are already running on the main CPU cluster. In practice this means that a second stage barebox will reuse the DT of the first stage, instead of using it's own.

* ARM: Kconfig: remove stale option CPU_V7_DCACHE_SKIPLucas Stach2015-03-021-8/+0
| | | | | | | | | | | I stumbled across this option a few times already and always found it to be at least confusing when and why it should be enabled. Since commit b7451329b5d2 (ARM: OMAP3: invalidate L2 cache using ROM API) it is actually unused and only adds confusion. Better remove it.

* ARM Samsung: fix booting from NAND without pblMichael Olbrich2015-02-251-3/+2
| | | | | | | | | This was broken in 558d72dc5116 (ARM Samsung: fix booting from NAND with pbl). '_text' is TEXT_BASE when building without pbl and (TEXT_BASE - SZ_2M) when building with pbl, so this works in both cases.

Right now there are three parameters: - has_battery - true when this board has a battery. - use_battery_input - true when this board is supplied from the battery input, but has a DC source instead of a real battery - use_5v_input - true when this board can use the 5V input The third one is introduced with this patch and allow to boot a board from 5v (USB) source only. The main necessary change this needs is that the DC-DC converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of HW_POWER_DCDC4P2) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
