On CPM, the RISC core is a lot more efficiant when doing transfers
in 16-bits chunks than in 8-bits chunks, but unfortunately the
words need to be byte swapped.
So, for large tranfers with an even size, allocate a temporary
buffer and byte-swap data before and after transfer.
This change allows setting higher speed for transfer. For instance
on an MPC 8xx (CPM1 comms RISC processor), the documentation tells
that transfer in byte mode at 1 kbit/s uses 0.200% of CPM load
at 25 MHz while a word transfer at the same speed uses 0.032%
of CPM load. This means the speed can be 6 times higher in
word mode for the same CPM load.
For small transfers, the load reduction is not worth the CPU load
required to allocate the temporary buffer, so do it only when data
size is over 64 bytes.

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.
Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.
So add a special GPIO driver that simulates GPIOs for those chipselect.

xfer ops can be passed a NULL input or output buffer. At the
time being the driver ignores it and overwrites memory at 0.
Define a dummy buffer and use it when either input or output
buffer is NULL. Bail out when both are NULL as it shouldn't.

Currently, fastboot protocol in U-Boot has no opportunity
to execute vendor custom code with verifed boot. This patch
introduce new fastboot subcommand fastboot oem board:<cmd>,
which allow to run custom oem_board function.
Default implementation is __weak. Vendor must redefine it in
board/ folder with his own logic.
For example, some vendors have their custom nand/emmc partition
flashing or erasing. Here some typical command for such use cases:
- flashing:
$ fastboot stage bootloader.img
$ fastboot oem board:write_bootloader

now it takes 110ms (and 419 writes (of which 386 64k)).
sendfile is much more appropriate for this and is done in one syscall,
but doesn't bring any significant speedups over 64k r/w

This patch series is needed to get U-Boot to boot from a ZFS filesystem
on an aarch64 computer. Some of the patches are not architecture specific
and would be needed to boot ZFS on other platforms as well. The ZFS
support in U-Boot hasn't been substantively touched in several years and
to me it seems like it must have been broken for a long time on all
platforms, but I have only tested on aarch64.
Since there doesn't seem to be a mantainer for this area who I can cc,
I'm hoping these patches get seen and pulled in by a general U-Boot
maintainer.
[trini: Per Igor's comment and Phaedrus agreement, dropped his Tested-by
on the patches themselves]
Without this patch, the while loop being modified goes on infinitely,
but with the patch I am able to boot linux on zfs on a jetson tx2 nx.
It seems like this code was never tested because the logic is clearly
wrong. The function do_div(a,b) does a division that modifies the first
parameter to have a = a / b, and returns the remainder of the division.
So clearly in the usual case when file->offset = 0, the line
"blkid = do_div(blkid, blksz);" just results in blkid being set to zero
on every iteration of the loop, rather than being incremented as blocks
are read. Hence the zeroth block is read over and over and this becomes
an infinite loop.
So instead capture the remainder of the division in a "blkoff" variable,
and use that to properly calculate the memory address to move from in
memmove() below.
For example, if file->offset were 1337, on the first iteration of the
loop blkid would be 0 and blkoff would be 1337. If the blksz is 131072
(as it was for me), that amount of data would be copied into
data->file_buf. movesize would be 131072 - 1337 = 129735 so 129735 bytes
would be moved into buf. On the second iteration of the loop (assuming
there is one), red would be 129735, blkid would be 1, blkoff would be 0,
and 131072 bytes would be copied into buf. And so on...
