While sandbox works OK without the special-case code, it does result in

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 0bc8f640a4.
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.

Since commit 2614a20847 ("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 SEGV
Turns out that the word-based byte-swapping loop in omapimage.c is to
blame. With the loop condition
while (swapped <= (sbuf->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.

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.
