      bl2-el3: Mark all the assembly functions in bl2 at el3 · 487d3bf2
      Roberto Vargas authored
      
      
      When BL2_AT_EL3 option is enabled some platforms are going to
      need a resident part in BL2 because the boot rom may jump to it
      after a reset. This patch introduces __TEXT_RESIDENT_START__ and
      __TEXT_RESIDENT_END__ linker symbols that mark the resident region.

      Mark functions defined in assembly files · d1f7292e
      Roberto Vargas authored
      
      
      This patch change the name of the section containing the functions
      defined in assembly files from text.* to text.asm.*. This change
      makes possible to select in the linker script the functions
      defined in those files.

      bl2-el3: Add BL2 at EL3 support in FVP · 81528dbc
      Roberto Vargas authored
      
      
      This patch add supports for the new API added for BL2 at EL3 for
      FVP. We don't have a non-TF Boot ROM for FVP, but this option can be
      tested setting specific parameters in the model.
      
      The bl2 image is loaded directly in memory instead of being loaded
      by a non-TF Boot ROM and the reset address is changed:
      
      	--data cluster0.cpu0=bl2.bin@0x4001000
      	-C cluster0.cpu0.RVBAR=0x4001000
      
      These parameters mean that in the cold boot path the processor will
      jump to BL2 again. For this reason, BL2 is loaded in dram in this
      case, to avoid other images reclaiming BL2 memory.

      bl2-el3: Add BL2_EL3 image · b1d27b48
      Roberto Vargas authored
      
      
      This patch enables BL2 to execute at the highest exception level
      without any dependancy on TF BL1. This enables platforms which already
      have a non-TF Boot ROM to directly load and execute BL2 and subsequent BL
      stages without need for BL1.  This is not currently possible because
      BL2 executes at S-EL1 and cannot jump straight to EL3.

      io: block: fix block_read/write may read/write overlap buffer · e19e40af
      Roberto Vargas authored
      
      
      The block operations were trying to optimize the number of memory
      copies, and it tried to use directly the buffer supplied by the user
      to them. This was a mistake because it created too many corner cases:
      
      	1- It was possible to generate unaligned
      	   operations to unaligned buffers. Drivers that were using
      	   DMA transfer failed in that case.
      
      	2- It was possible to generate read operations
      	   with sizes that weren't a multiple of the block size. Some
      	   low level drivers assumed that condition and they calculated
      	   the number of blocks dividing the number of bytes by the
      	   size of the block, without considering the remaining bytes.
      
      	3- The block_* operations didn't control the
      	   number of bytes actually copied to memory, because the
      	   low level drivers were writing directly to the user buffer.
      
      This patch rewrite block_read and block_write to use always the device
      buffer, which the platform ensures that has the correct aligment and
      the correct size.
