x86: use EFI calling convention for efi_main on x86_64
UEFI specifies the calling convention used in Microsoft compilers;
first arguments of a function are passed in (%rcx, %rdx, %r8, %r9).
All other compilers use System V ABI by default, passing first integer
arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9).
These ABI also specify different sets of registers that must be preserved
across function calls (callee-saved).
GCC allows using the Microsoft calling convention by adding the ms_abi
attribute to a function declaration.
Current EFI implementation in U-Boot specifies EFIAPI for efi_main()
in the test apps but uses default calling convention in lib/efi.

arm64: zynqmp: accept an absolute path for PMUFW_INIT_FILE
The value of PMUFW_INIT_FILE is prefixed with "$(srctree)/", thus
forcing it to be a relative path inside the U-Boot source tree. Since
the PMUFW is a binary file generated outside of U-Boot, the PMUFW
binary must be copied inside the U-Boot source tree before the
build.
This generates a few problems:
* if the source tree is shared among different out-of-tree builds,
they will pollute (and potentially corrupt) each other
* the source tree cannot be read-only
* any buildsystem must add a command to copy the PMUFW binary
* putting an externally-generated binary in the source tree is ugly
as hell
Avoid these problems by accepting an absolute path for
PMUFW_INIT_FILE. This would be as simple as removing the "$(srctree)/"
prefix, but in order to keep backward compatibility we rather use the
shell and readlink to get the absolute path even when starting from a
relative path.
Since 'readlink -f' produces an empty string if the file does not
exist, we also add a check to ensure the file configured in
PMUFW_INIT_FILE exists. Otherwise the build would exit successfully,
but produce a boot.bin without PMUFW as if PMUFW_INIT_FILE were empty.
Tested in the 12 possible combinations of:
- PMUFW_INIT_FILE empty, relative, absolute, non-existing
- building in-tree, in subdir, in other directory

net: designware: set the PS bit when resetting DMA bus in MII configuration
On the SPEAr600 SoC, which has the dwmac1000 variant of the IP block,
the DMA reset never succeeds when a MII PHY is used (no problem with a
GMII PHY). The designware_eth_init() function sets the
DMAMAC_SRST bit in the DMA_BUS_MODE register, and then
polls until this bit clears. When a MII PHY is used, with the current
driver, this bit never clears and the driver therefore doesn't work.
The reason is that the PS bit of the GMAC_CONTROL register should be
correctly configured for the DMA reset to work. When the PS bit is 0,
it tells the MAC we have a GMII PHY, when the PS bit is 1, it tells
the MAC we have a MII PHY.
Doing a DMA reset clears all registers, so the PS bit is cleared as
well. This makes the DMA reset work fine with a GMII PHY. However,
with MII PHY, the PS bit should be set.
We have identified this issue thanks to two SPEAr600 platform:
- One equipped with a GMII PHY, with which the existing driver was
working fine.
- One equipped with a MII PHY, where the current driver fails because
the DMA reset times out.

"%s_aml_code" is in use, where the prefix is a lowered case base
name of the output file. In our case it will be "dsdt" producing
a name as "dsdt_aml_code".
The quick solution is to call sed which replaces new name by the
old one to keep compatibility with old version of iASL.
The long term solution would be to modify code to use the new name
because it is more scalable.
