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.

Microchip PIC32 has internal parallel flash (non-CFI compliant).
These flash devices do not support any identifier command so no
standard IDs. Added unique IDs to seperate these flash devices
from others supported by U-Boot.

Introduce parse_i2c_bus_addr() to generalize the parsing of i2c bus number and
i2c device address. This is done in preparation for merging layout aware and
layout unaware command parsing into one function.
No functional changes.

Introduce the (optional) eeprom print and eeprom update commands.
These commands are eeprom layout aware:
* The eeprom print command prints the contents of the eeprom in a human
readable way (eeprom layout fields, and data formatted to be fit for human
consumption).
* The eeprom update command allows user to update eeprom fields by specifying
the field name, and providing the new data in a human readable format (same
format as displayed by the eeprom print command).
* Both commands can either auto detect the layout, or be told which layout to
use.
New CONFIG options:
CONFIG_CMD_EEPROM_LAYOUT - enables commands.
CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported
Feature API:
__weak int parse_layout_version(char *str)
- override to provide your own layout name parsing
__weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
- override to setup the layout metadata based on the version
__weak int eeprom_layout_detect(unsigned char *data)
- override to provide your own algorithm for detecting layout version
eeprom_field.c
- contains various printing and updating functions for common types of
eeprom fields. Can be used for defining custom layouts.

The i2c_init function is always provided when CONFIG_SYS_I2C is

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:
clearfog : spl/u-boot-spl:all -1592 spl/u-boot-spl:text -1592

Binding an MMC device when CONFIG_BLK is enabled requires that a block

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
