* ARM: MMU: Fix memory reaching to the end of address spaceSascha Hauer2014-03-181-1/+1
| | | | | | | | | For memory reaching the end of the address space phys + bank->size overflows to 0. Fix this by right shifting phys and bank->size before adding them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Sean Cross <xobs@kosagi.com>
* ARM: MMU: Add some debugging aids and hintsSascha Hauer2014-03-171-2/+55
| | | | | | | | | | | | | - If we have no memory registered in mmu_init() it's a critical bug. panic in this case. - If we do not have a ttb when dma_alloc_coherent or remap_range is called it's also a critical bug. Panic in this case. - if find_pte is called with an address outside our memory banks dump the memory banks and the address to give more clue what went wrong. Also add some hints what might went wrong to the code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: socfpga: socrates: fix ENTRY_FUNCTIONSteffen Trumtrar2014-03-121-2/+0
| | | | | | | | | | | The commit ARM: Make ENTRY_FUNCTION more robust changed the behaviour of the ENTRY_FUNCTION. For the Socrates the call to __barebox_arm_head() was not removed. Do so now otherwise the Socrates will not be able to boot barebox. Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * tegra: add lowlevel delay functionLucas Stach2014-02-192-0/+49
| | | | | | | | | | | | | | | | | | For proper startup we need to give clocks and IO signals some time to stabilize. Tegra2 got away without them, but Tegra3 seems to be a bit pickier. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * tegra: rename board directory for Colibri T20Lucas Stach2014-02-176-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | For computer modules the naming standard is to have a single board directory named after the module and have all the baseboard support beneath it. Also change the CONFIG name, as we may want to build all the baseboards at once. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
