16fec9b0bc stm32mp1: remove the imply BOOTSTAGE
This patch is only a temporarily workaround for crash introduced by
commit ac9cd4805c ("bootstage: Correct relocation algorithm").

The crash occurs because the bootstage struct is not correctly aligned
when BOOTSTAGE feature is activated.

df81abda0e x86: Separate out U-Boot and device tree in ROM image
At present binman does not support updating a device tree that is part of
U-Boot (i.e u-boot.bin). Separate the entries into two so that we can get
updated entry information. This makes binman_entry_find() work correctly.

Do the same for SPL tool.

In both cases, group the two parts into a section so that SPL symbols get
the correct total size.

It may be possible for binman to handle this automatically at some point,
by ignoring u-boot.bin and always creating it from u-boot-nodtb.bin and
u-boot.dtb

77dd7c6854 x86: timer: use a timer base of 0
On x86 platforms the timer is reset to 0 when the SoC is reset. Having
this as the timer base is useful since it provides an indication of how
long it takes before U-Boot is running.

When U-Boot sets the timer base to something else, time is lost and we
no-longer have an accurate account of the time since reset. This
particularly affects bootstage.

Change the default to not read the timer base, leaving it at 0. Add an
option for when U-Boot is the secondary bootloader.

d496162c85 x86: spi: Add helper functions for Intel Fast SPI
Most x86 CPUs use a mechanism where the SPI flash is mapped into the very
top of 32-bit address space, so that it can be executed in place and read
simply by copying from memory. For an 8MB ROM the mapping starts at
0xff800000.

However some recent Intel CPUs do not use a simple 1:1 memory map. Instead
the map starts at a different address and not all of the SPI flash is
accessible through the map. This 'Fast SPI' feature requires that U-Boot
check the location of the map. It is also possible (optionally) to read
from the SPI flash using a driver.

Add support for booting from Fast SPI. The memory-mapped version is used
by both TPL and SPL on Apollo Lake.

In respect of a SPI flash driver, the actual SPI driver is ich.c - this
just adds a few helper functions and definitions.

This is used by Apollo Lake.

Add a wait option to smp_call_function() to wait for the secondary harts
to acknowledge the call-function request. The request is considered to
be acknowledged once each secondary hart has cleared the corresponding

As part of the call-function request, the secondary harts invalidate the
instruction cache after clearing the IPI. This adds a delay between
acknowledgment (clear IPI) and fulfillment (call function) of the
request. We want to use the acknowledgment to be able to judge when the
request has been completed. Remove the delay by clearing the IPI after
cache invalidation and just before calling the function from the
request.

6b20dc165e riscv: increase stack size to avoid a stack overflow during distro boot
This fixes a problem, where booting Linux using distro boot will
sometimes lead to an invalid instruction exception on the main hart. The
secondary harts are not affected and boot Linux successfully. The root
cause of this problem is a stack overflow on the main hart.

With distro boot, the current default stack size of 8KiB on RISC-V is
not sufficient and will cause a stack overflow. The stacks are allocated
sequentially. In the case of a stack overflow the stack of the main hart
can reach into that of another hart and be corrupted.

The stack overflow previously did not cause any problems, because only
stack frames, which are not used anymore since the hart enters Linux,
were corrupted. Starting with GCC 9, the stack usage has decreased. Now,
only the most recent stack frame overflows into the stack of a secondary
hart and is corrupted. The illegal instruction exception is caused by
the secondary hart overwriting the return address in the stack frame of
the main hart with an address that does not include valid code.

Increase the default stack size of each hart to 16KiB to avoid this
problem.

The commit 1b42ab3eda ("ARM: DRA7: Fixup DSPEVE, IVA and GPU clock

family of SoCs.

The DSPs on DRA76xP/DRA77xP SoCs (DRA76x ACD package SoCs) though
provide a higher performance and can run at a higher clock frequency
of 850 MHz at OPP_HIGH instead of 750 MHz. Fix up the logic to use the
correct clock rates on these SoCs. Note that this higher clock rate is
not applicable to other Jacinto 6 Plus SoCs (DRA75xP/DRA74xP SoCs or
AM574x SoCs) that follow the ABZ package.

    arch-$(CONFIG_CPU_ARM1176)     =-march=armv5t

6a4b07e086 imx8m: fix rom version check to unbreak some B0 chips
Recently the version check was improved to be able to determine that
we're running on SoC revision 2.1.  A check for B0 was tightened so
that it now must equal 0x20 instead of being bigger than 0x20.  On
some B0 chips the value returned is 0x1020 instead of 0x20.  This
means even though it's B0, the check will fail and code relying on
the correct chip revision will make wrong decisions.  There is no
documentation of those bits, but it seems that NXP always uses a
byte to encode the revision.  Thus remove the upper bits to fix the
regression.

c671d8af0b board: colibri_imx7: reserve DDR memory for Cortex-M4
i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for
the rpmsg communication. Both use cases need a fixed location of
memory reserved. For the rpmsg use case the reserved area needs
to be in sync with the kernel's hardcoded vring descriptor location.

Use the linux,usable-memory property to carve out 1MB of memory
in case the M4 core is running. Also make sure that the i.MX 7
specific rpmsg driver does not get loaded in case we do not carve
out memory.

instead of UART2 (used for MMC) and UART5.

Make it possible to use UART3 as early debug output, with the associated
clock and pinmux configuration. Two sets of output pins are supported (M0/M1).

Future users should also note that the pinmux default in the dts is to use
the M1 pins while the Kconfig option takes M0 as a default.

The 'sf' command is not supposed to rely on the MTD stack, but both
'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite
their location, these functions do not depend at all on the MTD
stack.

This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is
selected, which is inconsistent with the current situation. Solve this
by moving these three functions (which are only used by the above two
commands) out of mtd_uboot.c and put them in a C file only compiled
with cmd/sf.c and cmd/nand.c.

97a72bc286 ARM: socfpga: Purge pending transactions upon enabling bridges on Gen5
On Gen5, when the FPGA is loaded and there was some prior interaction
between the HPS and the FPGA via bridges (e.g. Linux was running and
using some of the IPs in the FPGA) followed by warm reset, it has been
observed that there might be outstanding unfinished transactions. This
leads to an obscure misbehavior of the bridge.

When the bridge is enabled again in U-Boot and there are outstanding
transactions, a read from within the bridge address range would return
a result of the previous read instead. Example:
=> bridge enable ; md 0xff200000 1
ff200000: 1234abcd
=> bridge enable ; md 0xff200010 1
ff200010: 5678dcba <------- this is in fact a value which is stored in
                            a memory at 0xff200000
=> bridge enable ; md 0xff200000 1
ff200000: 90effe09 <------- this is in fact a value which is stored in
                            a memory at 0xff200010
and so it continues. Issuing a write does lock the system up completely.

This patch opens the FPGA bridges in 'bridge enable' command, the tears
them down again, and then opens them again. This allows these outstanding
transactions to complete and makes this misbehavior go away.

However, it is not entirely clear whether this is the correct solution.

As part of loading trustedfirmware, the SPL is required to place portions
of code into the socs sram but the mmc controllers can only do dma
transfers into the regular memory, not sram.

The results of this are not directly visible in u-boot itself, but
manifest as security-relate cpu aborts during boot of for example Linux.

There were a number of attempts to solve this elegantly but so far
discussion is still ongoing, so to make the board at least boot correctly
put both mmc controllers into fifo-mode, which also circumvents the
issue for now.

d47a774680 arm: arm11: allow unaligned memory access
The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.

This patch implements the function unaligned_access() to set the enable
unaligned data support flag and to clear the aligned flag in the system
control register (SCTLR). It is called when UEFI related commands like
bootefi are invoked.
