2014-04-11ArmPkg: Fixed GetEnvironmentVariable() when the UEFI Variable did not existOlivier Martin
The function was allocating a buffer for the read value from the UEFI Variable. But it was returning the pointer of the default value when the variable was not present. It could cause error when the default value and the returned value were free when these addresses were the same (double FreePool on the same address).

Part of the change to ArmPkg/Library/BdsLib/BdsLinuxLoader.c causes A9 to hang when booting the kernel, so I reverted the change that caused the problem. Signed-off-by: Ryan Harkin <ryan.harkin@linaro.org> Signed-off-by: Steven Kinney <steven.kinney@linaro.org>
2014-04-02ArmPlatformPkg/Bds: skip initrd if not foundRyan Harkin
When loading a Linux image, if the initrd is not found, we will display an error, but attempt to load the kernel anyway. Previous behaviour dropped the user back to the menu, thus allowing them to update the config. However, this does not suit booting in automated environments where test images may or may not have an initrd. Example, Ubuntu and Android images require an initrd; OpenEmbedded images do not.

2014-03-26ArmPkg/ArmLib: Correct Error Handling in AArch64Olivier Martin
There are several instances of asserts which do not also handle the error condition in Release builds. Because these functions are called in different location of the code and their parameters might change during the execution, it is safer to handle the error.

2014-03-01ArmPkg: Replace single dead loop.Olivier Martin
Several assembler macros use a loop at the label "dead" to trap an error. This is difficult to debug as there is no indication of how one arrived at the loop.

Update the LastBlockEntry return value when allocating a new page table block and the parent page table entry is not valid. Discovered when producing page table entries for a memory region that spans multiple page table entries of a parent page table block. Not very memory space efficient because the rest of the code could calculate a required page level that is deeper than some blocks of the memory region might require.
