It's usually a common pattern to free() the memory that we allocated.
Implement this here to stop leaking memory.

Currently, flash quad bit is set in "spi_flash_validate_params" and later
at the end in the same api, we write 0 to status register for few flashes,
thereby overriding the quad bit set. This fix moves the quad bit setting
outside this api in "spi_flash_probe_slave"

SPI driver perform its operation(read/write) on 64KB buffer chunk for data
greater than 64KB. This buffer chunk is allocated from system heap.
During SPL boot, 768KB of data is read from SPI flash.
Here, heap size may not be sufficient enough to full-fill 64KB buffer
requirement of SPI driver. So break down u-boot read operation at 8KB of chunk.
Also, fix a warning i.e. "unused variable buf" during CONFIG_FSL_CORENET

The commit 6af8dc3ebccb3b1e4b2e479315e49545e7f53150 broke support for
S25FL032P and S25FL064P by carelessly removing the code handling special
page size for these two SPI NOR flashes and unifying the code under the
assumption that Extended JEDEC ID of 0x4d00 always implies 512b page size.
Add special case handling for these two SPI NOR flashes.

This adds a SPI flash driver which simulates SPI flash clients.
Currently supports the bare min that U-Boot requires: you can
probe, read, erase, and write. Should be easy to extend to make
it behave more exactly like a real SPI flash, but this is good
enough to merge now.

Existing eSPI SPL framework assumes booting from spi-image
with boot_format header which contains final u-boot Image
offset and size. No such header is present in case of
corenet devices like T1040 as corenet deivces use PBI-RCW
based intialization.
So, for corenet deives, SPL bootloader use values provided
at compilation time. These values can be defined in board
specific config file.

Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.
This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of "memory_map" flag.
- Add support to communicate to the driver that memory mapped
transfer is to be started through introduction of new flags like
"SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END".
This will enable the spi controller to do memory mapped configurations
if required.
