When the base registers are read from device tree the base is not
0x48030100 as the driver expects, but 0x48030000, resulting in
non functioning SPI. To deal with this, use same idea as how this
is done in the linux kernel (drivers/spi/spi-omap2-mcspi.c) and
add a structure with a field that is used to shift the registers
on these systems.

The correct pinctrl is handled automatically so we don't need to do it in

PIC32 internal flash devices are parallel NOR flash divided into
number of banks to allow erase-programming in one while fetch and
execution continues on other. As the flash banks are memory mapped
stored code can be executed directly from flash (XIP), also there
is additional hardware logic to prefetch and cache contents to
improve execution performance. These flash can also be used to
store user data (like environment).
Flash erase and programming are handled by on-chip NVM controller.
Driver implemented driver model but MTD is not really support.

For reason unknown, recently, the DDR init code writers are really fond
of hiding some small floating point operating deep in their creations.
This patch removes one from the Marvell A38x code.
Instead of returning size of chip as float from ddr3_get_device_size()
in GiB units, return it as int in MiB units. Since this would interfere
with the huge switch code in ddr3_calc_mem_cs_size(), rework the code
to match the change.
Before this patch, the cs_mem_size variable could have these values:
( { 16, 32 } x { 8, 16 } x { 0.01, 0.5, 1, 2, 4, 8 } ) / 8 =
{ 0.000000, 0.001250, 0.002500, 0.005000, 0.062500, 0.125000,
0.250000, 0.500000, 1.000000, 2.000000, 4.000000, }
The switch code checked for a subset of the resulting RAM sizes, which
is in range 128 MiB ... 2048 MiB.
With this patch, the cs_mem_size variable can have these values:
( { 16, 32 } x { 8, 16 } x { 0, 512, 1024, 2048, 4096, 8192 } ) / 8 =
{ 0, 64, 128, 256, 512, 1024, 2048, 4096 }
To retain previous behavior, filter out 0 MiB (invalid size), 64 MiB
and 4096 MiB options.
Removing the floating point stuff also saves 1.5k from text segment:

Add support for enabling CONFIG_BLK with MMC. This involves changing a
few functions to use struct udevice and adding a MMC block device driver.
Signed-off-by: Simon Glass <sjg@chromium.org>

Binding an MMC device when CONFIG_BLK is enabled requires that a block
device be bound as a child of the MMC device. Add a function to do this.
The mmc_create() method will be used only when DM_BLK is disabled.
Add an unbind method also.

At present the MMC subsystem maintains its own list of MMC devices. This
cannot work with driver model, which needs to maintain this itself. Move the
list code into a separate 'legacy' file. The core MMC code remains, and will
be shared with the driver-model implementation.

Some devices have a name that is stored in allocated memory. At present
