dc23c27aa5 arm: remove ARCH_ROCKCHIP macro in common code
This is fix to:
e2a12f590d rockchip: use 'arch-rockchip' as header file path

The V2 of origin patch set has fix this, but we merge V1 by
mistake, so lets correct it.

add4967124 arch: armv8: Provide a way to disable cache maintenance ops
On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache
maintenance operations being done to support non-coherent platforms
causes issues.

For example, here is how U-Boot prepares/handles a buffer to receive
data from a device (DMA Write). This may vary slightly depending on the
driver framework:

	Start DMA to write to destination buffer
	Wait for DMA to be done (dma_receive()/dma_memcpy())
	Invalidate destination buffer (invalidate_dcache_range())
	Read from destination buffer

The invalidate after the DMA is needed in order to read latest data from
memory that’s updated by DMA write. Also, in case random prefetch has
pulled in buffer data during the “wait for DMA” before the DMA has
written to it. This works well for non-coherent architectures.

In case of coherent architecture with L3 cache, DMA write would directly
update L3 cache contents (assuming cacheline is present in L3) without
updating the DDR memory. So invalidate after “wait for DMA” in above
sequence would discard latest data and read will cause stale data to be
fetched from DDR. Therefore invalidate after “wait for DMA” is not
always correct on coherent architecture.

Therefore, provide a Kconfig option to disable cache maintenance ops on
coherent architectures. This has added benefit of improving the
performance of DMA transfers as we no longer need to invalidate/flush
individual cache lines(especially for buffer thats several KBs in size).

In order to facilitate use of same Kconfig across different
architecture, I have added the symbol to top level arch/Kconfig file.
Patch currently disables cache maintenance ops for arm64 only.
flush_dcache_all() and invalidate_dcache_all() are exclusively used
during enabling/disabling dcache and hence are not disabled.

25c07c72fd ARMv8: PSCI: Fix PSCI_TABLE relocation issue
This fixes relaction isses with the PSCI_TABLE entries in
the psci_32_table and psci_64_table.

When using 32-bit adress pointers relocation was not being applied to
the tables, causing PSCI handlers to point to the un-relocated code
area. By using 64-bit data relocation is properly applied. The
handlers are thus in the "secure data" area, which is protected by
/memreserve/ in the FDT.

1721b82c1f arm: fix hvc call
HVC call makes use of 6 mandatory arguments rather than 7 in the same way
as SMC calls. The 7th argument is optional (Client ID) for both HVC and
SMC but is implemented as 16-bit parameter and register R7 or W7. The aim
of this patch is just fix compilation error due to an invalid asm code in
the HVC call so that's why the 7th argument is removed.

The issue does not report any error in a normal build as hvc_call is not
used at all and is optimized by the compiler. Using -O0 triggers the
error so the patch is intended to fix issues on a ongoing effor to build
U-Boot with -O0.

ef331e3685 armv8: Disable exception vectors in SPL by default
Commit 1416e2d225 ("armv8: make SPL exception vectors optional") had a
typo in it which effectively disabled exception handling in SPL code always.

Since nobody complained, I guess we may as well disable exception handling
in SPL always by default.

So fix the bug to make the config option effective, but disable exception
handling in SPL by default. This gets us to the same functionality as before
by default, but with much less code included in the binary.

2e53759dc6 armv8: fsl-layerscape: reorder rgmii dpmacs' enablement
some dpmacs in armv8a based freescale layerscape SOCs can be
configured via both serdes(sgmii, xfi, xlaui etc) bits and via
EC*_PMUX(rgmii) bits in RCW.
e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from
serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
Now if a dpmac is enabled by serdes bits then it takes precedence
over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol
that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII,
then the dpmac is SGMII and not RGMII.

Therefore, move the fsl_rgmii_init after fsl_serdes_init. in
fsl_rgmii_init function of SOC, we will check if the dpmac is enabled
or not? if it is (fsl_serdes_init has already enabled the dpmac), then
don't enable it.

81ea00838c efi_loader: PSCI reset and shutdown
When an operating system started via bootefi tries to reset or power off
this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system
the actual reset relies on PSCI. Depending on whether the PSCI firmware
resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC
or an SMC command has to be issued.

The current implementation always uses SMC. This results in crashes on
systems where the PSCI firmware is implemented in the hypervisor, e.g.
qemu-arm64_defconfig.

The logic to decide which call is needed based on the device tree is
already implemented in the PSCI firmware driver. During the EFI runtime
the device driver model is not available. But we can minimize code
duplication by merging the EFI runtime reset and poweroff code with
the PSCI firmware driver.

As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff
and reset_misc routines let's move them into the same code module.

5860bc16b9 arm64: zynqmp: Add new command for TCM initialization
This patch adds new zynqmp command "zynqmp tcminit mode" to
initialize TCM. TCM needs to be initialized before accessing
to avoid ECC errors. This new command helps to perform
the same. It also makes tcm_init() as global and uses it for
doing the TCM initialization.
