[U-Boot] [PATCH v4 0/8] Extend LPC32xx functionality and add LPC32xx-based work_92015 board

[Albert ARIBAUD (3ADEV)]

This series extends functionality for the LPC32xx platform and
introduces the WORK Microwave work_92105 board which makes use
of the extended functionality.

NOTES:

A - I2C driver remains non-DM

During v2 review, it was suggested to move to DM for I2C. However,
this caused issues with the 'date', 'dtt' and 'eeprom' commands which
are configured in this board. Therefore the I2C move to DM was not
done.

B - Some checkpatch diagnostics are not fixed

The following warnings checkpatch warnings and checks were not fixed:

1. "warning: arch/arm/Kconfig,135: please write a paragraph that describes
    the config symbol fully"
   Other symbols in the same file have no description either. For
   consistency, I did not add the requested description.

1. "check: include/configs/work_92105.h,185: spaces required around that
   ':' (ctx:VxV)
   (5 occurrences on the same line)
   This is due to the value of CONFIG_ETHADDR not being in quotes. As it
   never is in any other definition of CONFIG_ETHADDR, I left it
   unchanged.

Changes in v4:
- remove two debugging statements
- add __iomem to regs struct
- remove useless 'else return;'
- take BB marker out of free OOB area
- replace magic numbers in OOB reads/writes
- add timeouts in NAND loops
- use DIV_ROUND_UP where applicable
- fix erroneous comment
- skip bad blocks in SPL chainload loop

Changes in v3:
- move DM dependency constraint into Kconfig
- move regs pointer and function cache into private struct
- discourage readers from using functions implementation as an example
- move regs and functions in private struct
- remove script/Makefile.spl change
- use writel() in DRAM initialization code
- remove useless conditionals in dram.c
- fix and complete the board README
- remove redundant CONFIG_CMD_DM from config header file
- add a note re the hard-coded MAC address
- add 'single flashable file' make target

Changes in v2:
- move from legacy to Driver Model support
- added MUX setting for SSP0
- cosmetic: added a blank line before copyright
- move boot image generation to mkimage framework
