It is useful to display log messages on the console. Add a simple driver
to handle this.Note that this driver outputs to the console, which may be serial or

With clang this gives a warning because hubsts appears to be used before

The debug() macro now evaluates its expression so does not need #ifdef

While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.For ease of debugging it seems better to revert this change also.
This reverts commit d8c6fb8cedbc35eee27730a7fa544e499b3c81cc.

We cannot use sandbox memory at 0 since other things use memory at that
address. Move it up out of the way.Note that the pre-console buffer is currently disabled with sandbox, but
this change will avoid confusion if it is manually enabled.Signed-off-by: Simon Glass

The .probe_chip function is supposed to probe an i2c device on the bus to
determine whether a device is answering to a particular address.
at91_i2c_probe_chip() did not do anything resembling this and always
returned 0.It looks as though at91_i2c_probe_chip() was intended to be a .probe
function for the controller, as it was copied-and-pasted to become
at91_i2c_probe() in 0bc8f640a4d7ed.Removing the at91_i2c_probe_chip() function makes the higher layer
(i2c_probe_chip()) try a zero-length read transfer to test for the
presence of a device instead, which does work.Signed-off-by: Alan Ott

The driver must wait for TXRDY after each byte is pushed into
the i2c FIFO before pushing the next byte. Previously this was
not done for the first byte, causing a race condition with zeros
sometimes being sent for the next byte (which is typically the
first actual data byte).Signed-off-by: Alan Ott

Since commit 2614a208471e ("common: command: tempory buffer should
have size of command line buf"), there have been consistent Travis CI
failures on my builds (interestingly not for Tom, even though building
the same commit id) due to a SEGV in building the byteswapped
omapimage:
arm: pcm051_rev3
make[2]: *** [MLO.byteswap] Error 139
^^^ error code for a SEGVTurns out that the word-based byte-swapping loop in omapimage.c is to
blame. With the loop condition
while (swapped st_size / sizeof(uint32_t)))
there had been one-too-many iterations for all file sizes divisible by
the sizeof(uint32_t). I.e. we had 1 iteration for 0 bytes (and also 1
through 3 bytes) and 2 iterations at 4 bytes... clearly overshooting
on 0 and 4 bytes.This commit fixes the calculation of an up-rounded word-count and
makes sure to keep the zero-based loop-counter below the number of
words to be processed.References: 2614a20 ("common: command: tempory buffer should have size of command line buf")

Highlights for this release:
- Dynamic EFI object creation (lists instead of static arrays)
- EFI selftest improvements
- Minor fixes -
Commit f5a2a93892f ("efi_loader: consistently use efi_uintn_t in boot
services") changed the internal EFI API header without adapting its existing
EFI stub users. Let's adapt the EFI stub as well.Fixes: f5a2a93892f ("efi_loader: consistently use efi_uintn_t in boot services")

As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware
and a secondary BL32 firmware.
Since mid-2017, the reserved memory address of the BL31 firmware was moved
and grown for security reasons.But mainline U-Boot and Linux has the old address and size fixed.
These SoCs have a register interface to get the two firmware reserved
memory start and sizes.This patch adds a dynamic reservation of the memory zones in the device tree bootmem
reserved memory zone used by the kernel in early boot.
To be complete, the memory zones are also added to the EFI reserved zones.Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

In the moment our exception entry code needs 34 instructions, so we
can't use put it directly into the table entry, which offers "only"
32 instructions there. Right now we just put an unconditional branch
there, then use a macro to place the 34 instructions *per entry* after
that. That effectivly doubles the size of our exception table, which
is quite a waste, given that we use it mostly for debugging purposes.Since the register saving part is actually identical, let's just convert
that macro into a function, and "bl" into it directly from the exception
slot, of course after having saved at least the original LR.
This saves us about 950 bytes of code, which is quite a relief for some
tight SPLs, in particular the 64-bit Allwinner ones.Signed-off-by: Andre Przywara
