cfi_flash: add support for Spansion flash PPB sector protection

Erasing flash sectors protected with persistent protection bit (PPB)
mechanism on Spansion flash chips doesn't work. Add sector protection
status checking and sector lock and unlock commands to fix this.

mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashs

commit 54652991
Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips

fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads
to problems for smaller versions of this chip e.g. the 32Mbit version
with deviceid 0x16 on mgcoge. So move the code for this work around to
an own function and check previously manufacturer id and device id to
not break other flashes which don't need this work around.

Commit 8b5a02640adf77301f943e8754992c50df004e8a ("Makefile: cosmetic:
optimize usage of LIBS-y") broke the build of boards that have a board
vendor "common" directory, by introducing a space between "LIBS-" and

omap24xx_i2c: add 2-byte address support

Various devices like EEPROMs require 2-byte address support to
be properly accessed. This patch adds this support for OMAP2/3/4
I2C controller driver.
I've tested it with EEPROM (16 bit address) and TPS65217 chip
(8 bit address) on TI Beaglebone board.

Unfortunately I don't have access to any compatible hardware
with 16bit data register so I can't test if those #ifdef
clauses really work.

hawkboard/omapl-138: Add support for generating ais image for hawkboard

Parameters used for configuring certain SoC peripherals are parsed
from the cfg file and appended as part of the ais image's header. The
u-boot-spl.ais generated is flashed separately to the nand, so do not
delete the file after generation of u-boot.ais.

configuring the timing register as 0x08222204, where as currently it
configured to 0x00100084 in U-Boot. This issue was found out when
support for NAND SPL is added in U-Boot. Without this patch U-Boot
does not come up with SPL.
