2013-12-05rework general purpose registers save and restoreAchin Gupta
The runtime exception handling assembler code used magic numbers for saving and restoring the general purpose register context on stack memory. The memory is interpreted as a 'gp_regs' structure and the magic numbers are offsets to members of this structure. This patch replaces the magic number offsets with constants. It also adds compile time assertions to prevent an incorrect assembler view of this structure. Change-Id: Ibf125bfdd62ba3a33e58c5f1d71f8c229720781c

2013-12-05Properly initialise the C runtime environmentSandrine Bailleux
This patch makes sure the C runtime environment is properly initialised before executing any C code. - Zero-initialise NOBITS sections (e.g. the bss section). - Relocate BL1 data from ROM to RAM. Change-Id: I0da81b417b2f0d1f7ef667cc5131b1e47e22571f
2013-11-27AArch64: Remove EL-agnostic TLB helper functionsSandrine Bailleux
Also, don't invalidate the TLBs in disable_mmu() function, it's better to do it in enable_mmu() function just before actually enabling the MMU. Change-Id: Ib32d6660019b0b2c17254156aad4be67ab4970e1
2013-11-27Unmask SError and Debug exceptions.Sandrine Bailleux
Any asynchronous exception caused by the firmware should be handled in the firmware itself. For this reason, unmask SError exceptions (and Debug ones as well) on all boot paths. Also route external abort and SError interrupts to EL3, otherwise they will target EL1. Change-Id: I9c191d2d0dcfef85f265641c8460dfbb4d112092
