The QSPI controller in i.MX 6SoloX and Vybrid supports reading data using
IP register and AHB bus.
The original driver only supports reading data from IP interface. The IC
team suggests to use AHB read which is faster then IP read. Using AHB read,
we can directly memcpy, a "missed" access to the buffer will cause the
controller to clear the buffer and use the SEQID stored in bfgencr register
to initiate a read from flash device.
Since AHB bus is 64 bit width, we can not set MCR register using 32bit. In
order to minimize code change, redefine QSPI_MCR_END_CFD_LE to 64bit Little
endian but not 32bit Little endia.
Introduce a new configuration option CONFIG_SYS_FSL_QSPI_AHB. If want to
use AHB read, just define CONFIG_SYS_FSL_QSPI_AHB. If not, just ignore it.
Actually if Vybrid is migrated to use AHB read, this option can be removed and
IP read function can be discared. The reason to introduce this option
is that only i.MX SOC is tested in my side, no Vybrid platform for me.
In spi_setup_slave, the original piece code to set AHB is deleted, since
Vybrid platform does not use this to intiate AHB read. Instead, add
qspi_init_ahb_read function if defined CONFIG_SYS_FSL_QSPI_AHB.

To support bigger than 16MB size qspi flashes, spi framework uses bank
switch to access higher bank or lower bank.
In this patch, QSPI_CMD_BRRD, QSPI_CMD_BRWR, QSPI_CMD_WREAR, QSPI_CMD_RDEAR
is initialized in LUT register with related pad and length configuration.
qspi_op_pp is originally for page programming, this patch reuses this function
for bank register switch and renamed it with qspi_op_write.
Since bank or EAR register is only 1 byte length, however original qspi_op_pp
or now renamed qspi_op_write only support 4 bytes lenght as the access unit,
this will trigger data abort exception when access EAR or bank register.
This is because upper framework passes a 1 bytes pointer to qspi_op_write,
however qspi_op_write treat it as an int pointer. This patch fixes this for
accessing EAR or bank register.

Current code tries to find the highest valid fifo depth by checking the value
it wrote to DW_SPI_TXFLTR. There are a few problems in current code:
1) There is an off-by-one in dws->fifo_len setting because it assumes the latest
register write fails so the latest valid value should be fifo - 1.
2) We know the depth could be from 2 to 256 from HW spec, so it is not necessary
to test fifo == 257. In the case fifo is 257, it means the latest valid
setting is fifo = 256. So after the for loop iteration, we should check
fifo == 2 case instead of fifo == 257 if detecting the FIFO depth fails.
This patch fixes above issues.

RX and TX descriptor rings should be aligned to 256 byte boundaries. Use
the DEFINE_ALIGN_BUFFER() macro to define the buffers so that they don't
have to be manually aligned later on. Also make sure that the buffers do
align to cache-line boundaries in case the cache-line is higher than the
256 byte alignment requirements of the NIC.
Also add a warning if the cache-line size is larger than the descriptor
size, because the driver may discard changes to descriptors made by the
hardware when requeuing RX buffers.

In function dfu_get_buf(), the size of allocated buffer could
be defined by the env variable. The size from this variable
was passed for memalign() without checking its value.
And the the memalign will return non null pointer for size 0.
This could possibly cause data abort, so now the value of var
is checked before use. And if this variable is set to 0 then
the default size will be used.
This commit also changes the base passed to simple_strtoul()
to 0. Now decimal and hex values can be used for the variable
dfu_bufsiz.
