arm: caches: manage phys_addr_t overflow in mmu_set_region_dcache_behaviour
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 !!!

spi: sifive: Add spi-mem exec op
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.

in linux.
When defining spi_mem_op templates we don't necessarily know the size
that will be passed when the template is actually used, and basing the
supports_op() check on op->data.nbytes to know whether there will be
data transferred for a specific operation is not possible.
Add SPI_MEM_NO_DATA to the spi_mem_data_dir enum so that we can base

This also fixes a bug identified with the atmel-quaspi driver.
The spi-nor core, when erasing sectors, fills the spi_mem_op template
using SPI_MEM_OP_NO_DATA, which initializes all the data members with
value zero. This is wrong because data.dir is treated as SPI_MEM_DATA_IN,
which translates in our driver to read accesses for erases (RICR), while
the controller expects write accesses (WICR).
