0e028bf970 x86: doc: Remove stale sections of 64-bit support
There are some sections in current doc saying 64-bit is unsupported.
This apparently is out of date. Remove it.

dd4611dea4 x86: Ensure no instruction sets of MMX/SSE are generated in 64-bit build
With the '-march=core2' fix, it seems that we have some luck that
the 64-bit U-Boot boots again. However if we examine the disassembly
codes there are still SSE instructions elsewhere which means passing
cpu type to GCC is not enough to prevent it from generating these
instructions. A simple test case is doing a 'bootefi selftest' from
the U-Boot shell and it leads to a reset too.

The 'bootefi selftest' reset is even seen with the image created by
the relative older GCC 5.4.0, the one shipped by Ubuntu 16.04.

The reset actually originates from undefined instruction exception
caused by these SSE instructions. To keep U-Boot as a bootloader as
simple as possible, we don't want to handle such advanced SIMD stuff.
To make sure no MMX/SSE instruction sets are generated, tell GCC not
to do this. Note AVX is out of the question as CORE2 is old enough
to support AVX yet.

a139cc1865 x86: Specify -march=core2 to build 64-bit U-Boot proper
With newer kernel.org GCC (7.3.0 or 8.1.0), the u-boot.rom image
built for qemu-x86_64 target does not boot. It keeps resetting
soon after the 32-bit SPL jumps to 64-bit proper. Debugging shows
that the reset happens inside env_callback_init().

000000000113dd85 <env_callback_init>:
 113dd85:       41 54                   push   %r12
 113dd87:       55                      push   %rbp
 113dd88:       31 c0                   xor    %eax,%eax
 113dd8a:       53                      push   %rbx
 113dd8b:       0f 57 c0                xorps  %xmm0,%xmm0

Executing "xorps %xmm0,%xmm0" causes CPU to immediately reset.
However older GCC like 5.4.0 (the one shipped by Ubuntu 16.04)
does not generate such instructions that utilizes SSE for this
function - env_callback_init() and U-Boot boots without any issue.
Explicitly specifying -march=core2 for newer GCC allows U-Boot
proper to boot again. Examine assembly codes of env_callback_init
and there is no SSE instruction in that function hence U-Boot
continues to boot.

core2 seems to be the oldest arch in GCC that supports 64-bit.
Like 32-bit U-Boot build we use -march=i386 which is the most
conservative cpu type so that the image can run on any x86
processor, let's do the same for the 64-bit U-Boot build.

97d20f69f5 Enable CONFIG_TIMER_EARLY with bootstage
In initr_bootstage() we call bootstage_mark_name() which ends up calling
timer_get_us(). This call happens before initr_dm(), which inits driver
model.

On x86 we set gd->timer to NULL in the transition from board_init_f()
to board_init_r(). See board_init_f_r() for this assignment. So U-Boot
knows there is no timer available in the period immediately after
relocation.

On x86 the timer_get_us() call is implemented as calls to get_ticks() and
get_tbclk(). Both of these call dm_timer_init() to set up the timer, if
gd->timer is NULL and the early timer is not available.

However dm_timer_init() cannot succeed before initr_dm() is called.

So it seems that on x86 if we want to use CONFIG_BOOTSTAGE we must enable
CONFIG_TIMER_EARLY. Update the Kconfig to handle this.

Note: On most architectures we can rely on the pre-relocation memory still
being available, so that gd->timer pointers to a valid timer device and
everything works correctly. Admittedly this is not strictly correct since
the timer device is set up by pre-relocation U-Boot, but normally this is
fine. On x86 the 'CAR' (cache-as-RAM) memory used by pre-relocation U-Boot
disappears in board_init_f_r() and any attempt to access it will hang.
This is the reason why we must mark the timer as invalid when we get to
board_init_f_r().

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.

12ad2994a5 arm64: zynqmp: Move TCM initialization to a separate routine
This patch moves TCM initialization to a separate routine to
make it modular and can be reused if required. It also prints
warning message now as it writes to TCM.

ddccf5ef90 arm64: versal: Add Xilinx Versal Virtual QEMU board
Virtual QEMU board is generating DTB self and putting it to
VERSAL_QEMU_DTB_ADDR address.
Board is using CONFIG_OF_BOARD which ensures that u-boot is aligned with
board created by QEMU.

ec48b6c991 arm64: versal: Add support for new Xilinx Versal ACAPs
Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine
Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent
Engines with leading-edge memory and interfacing technologies to deliver
powerful heterogeneous acceleration for any application. The Versal AI
Core series has five devices, offering 128 to 400 AI Engines. The series
includes dual-core Arm Cortex™-A72 application processors, dual-core Arm
Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more
than 1,900 DSP engines optimized for high-precision floating point with
low latency.

The patch is adding necessary infrastructure in place without enabling
platform which is done in separate patch.

As observed with clang:
lib/efi_loader/efi_boottime.c:1624:7: warning: variable 'info'

      its condition is always false
                if (ret != EFI_SUCCESS)

lib/efi_loader/efi_boottime.c:1602:31: note: initialize the

        struct efi_loaded_image *info;

                                      = NULL

Rather than change how we unwind the function it makes the most sense to
initialize info to NULL so that we can continue to pass it to free().
