As noted in rtc_def.h, the tm_mon field in struct rtc_time is 1-12,
unlike in struct tm where it is 0-11. Currently, running "date" prints
the wrong

Solved the overflow on phys_addr_t type for start + size in
mmu_set_region_dcache_behaviour() function.
This overflow is avoided by dividing start and end by 2 before addition,
and we only expecting that start and size are even.
This patch doesn't change the current function behavior if the
parameters (start or size) are not aligned on MMU_SECTION_SIZE.
For example, this overflow occurs on ARM32 with:
start = 0xC0000000 and size = 0x40000000
then start + size = 0x100000000 and end = 0x0.
For information the function behavior change with risk of regression,
if we just shift start and size before the addition.
Example with 2MB section size:
MMU_SECTION_SIZE 0x200000 and MMU_SECTION_SHIFT = 21
with start = 0x1000000, size = 0x1000000,
- with the proposed patch, start = 0 and end = 0x1 as previously
- with the more simple patch:
end = (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT)
the value of end change:
start >> 21 = 0, size >> 21 = 0 and end = 0x0 !!!

Add U-Boot specific dts file for hifive-unleashed-a00, this

Added spi2 alias for qspi2 as an initial u-boot specific

spi probing in current dm model is very much rely on aliases
numbering. Even though the qspi2 can't come under any associated
spi nor flash it would require to specify the same to make proper
binding happen for other spi slaves.

The guessed reason is that the existing logic of filling
tx fifo with data, rx fifo with NULL for tx transfer and
filling rx fifo with data, tx fifo with NULL for rx transfer
is not clear enough to support the Quad Page Program.
SiFive SPI controllers have specific sets of watermark
registers and SPI I/O directions bits in order to program
SPI controllers clear enough to support all sets of operating
modes.
Here is the exact programing sequence that would follow on this
patch and tested via SPI-NOR and MMC_SPI.
- set the frame format proto, endian
- set the frame format dir, set it for tx and clear it for rx
- TX transfer:
fill tx fifo with data.
wait for TX watermark bit to clear.
- RX transfer:
fill tx fifo with 0xff.
write nbytes to rx watermark register
wait for rx watermark bit to clear.
read the rx fifo data.
So, this patch adopts this program sequence and fixes the existing
I/O direction bit.

SiFive SPI controller has a proto bit field in frame format
register which would be used to configure the SPI I/O protocol
lines used on specific transfer.
Right now the driver is configuring this proto using slave->mode,
for all types of transctions. This makes the driver unable to
function since the proto needs to configure dynamically for
each and every transaction separately at runtime.
Now, the controller driver supports per transfer via spi-mem
exec_opo, so add the fmt_proto flag and fill the per transfer
buswidth so that the controller configures the proto bit at
runtime.
This patch fixes the SPI controller works with SPI NOR flash
on quad read with page program.

SiFive SPI controller is responsible to handle the
slave devices like mmc spi and spi nor flash.
The controller is designed such a way that it would
handle the slave transactions based on the I/O protocol
numbers, example if spi nor slave send quad write opcode
it has to send alone with I/O protocol number of 4 and
if it try to send data it has to send I/O protocol number
along with 4 line data.
But the current spi-xfer code from spi-mem is combining
the opcode and address in a single transaction, so the
SPI controller will be unable to identify the I/O protocol
number of opcode vs address.
So, add the spi-mem exec_op with spi-xfer of opcode, address
and data as a separate transaction. This doesn't remove
the .xfer of dm_spi_ops since mmc spi will make use of it.
Note: This code might have moved to the spi-mem core area
once we have done the dedicated tests on other controllers
and have real reason to move.

With chromebook_coral we normally run TPL->SPL->U-Boot. This is the
'bare metal' case.
When running from coreboot we put u-boot.bin in the RW_LEGACY portion
of the image, e.g. with:
cbfstool image-coral.serial.bin add-flat-binary -r RW_LEGACY \
-f /tmp/b/chromebook_coral/u-boot.bin -n altfw/u-boot \
-c lzma -l 0x1110000 -e 0x1110000

It is useful to be able to boot the same x86 image on a device with or
without a first-stage bootloader. For example, with chromebook_coral, it
is helpful for testing to be able to boot the same U-Boot (complete with
FSP) on bare metal and from coreboot. It allows checking of things like
CPU speed, comparing registers, ACPI tables and the like.
When U-Boot is not the first-stage bootloader much of this code is not
needed and can break booting. Add checks for this to the FSP code.
Rather than checking for the amount of available SDRAM, just use 1GB in
this situation, which should be safe. Using 2GB may run into a memory
hole on some SoCs.
