Copied the GPIO configurator written for the Linux kernel.
The Nomadik db8500 GPIO driver. Purpose is to be able
to just cut-n-paste the GPIO config from Linux to U-boot.
Also at the same time remove the obsolete and old
gpio_alt_funcenable/disable methods.
Now all is configured using a table in u8500.c.
Now drivers doesn't have to worry about setting up the GPIO pins.
Actually no driver today uses GPIO pins directly, only via
hardware blocks within db8500. Functions are still added
to be able to interact directly with a GPIO pin. This also
cleaned up a lot of driver by not having to bit manipulate GPIO
registers them self.
The new driver is called db8500_gpio and placed in driver/gpio/.
Functions are in include/db8500_gpio.h:
void db8500_gpio_set_pull(unsigned gpio, enum db8500_gpio_pull pull);
void db8500_gpio_make_input(unsigned gpio);
int db8500_gpio_get_input(unsigned gpio);
void db8500_gpio_make_output(unsigned gpio, int val);
void db8500_gpio_set_output(unsigned gpio, int val);
And for the configurator in include/db8500_pincfg.h:
void db8500_gpio_config_pins(pin_cfg_t *cfgs, size_t num);
All in all the final binary size has decreased.
This is only done for db8500 nomadik GPIO. The code for gpio
expanders has not been touched.
All references to Nomadik has been removed in this driver.
Only db8500 is left.

Moved u8500_is_earlydrop() and cpu_is_u8500*() to
include/asm-arm/arch-db8500/cpu.h.
They are kept in cpu.h as the functions are very small and
should be inlined with each use of them.
The final binary actually also became around 100 bytes smaller.

common.h and gpio.h were present in the u8500 board directory and in the
SoC include directory include/asm-arch/arch-stw8500.
This patch removes the duplicates in the board directory and replaces
all "common.h" and "gpio.h" with <asm/arch/common.h> and
<asm/arch/gpio.h>, respectively.

Fixes sd card init that did not initialize ddr_en.
This made sd fail init when previous contents in ddr_en was not 0.

Moved splash start to just after emmc init to minimize time to splash.
Changed behaviour so that all SW is loaded after splash and splash is
not loaded if it is itp.

This adds functionality to load and execute modem in an early stage just after
eMMC init.
It also flushes ISSW since this will be removed in Xloader
This patch depends on an updated Xloader that doesn't load modem, ipl and
doesn't flush ISSW.

This adds functionality to load and execute ITP in an early stage just after eMMC init.
eMMC init was moved to mmc_host.c since it fits better there and is needed in
order to access ITP before loading env.
Flag for functionality is CONFIG_ITP_LOAD.
This functionailty depends on CONFIG_TOC_PARTITION

MMC has been updated with several improvements. Primarily MMC
performance has been improved by using assembler code for low
level FIFO handling. Also some MMC functionality has been added,
e.g. support for DDR and reliable write.
Data and command delay times were incremented, otherwise hangups and
timeouts were observed.
Tested on HREF+ 1.1 V21 and HREF+ 1.1 V32 (Micron PoP).
Following WP depends on this change (more reliable SD card write
support):

- Add cpu_is_u8500v2() for identification: ASICID has moved, so use
the MIDR for primary identification.
- Handle the changed MTU0 enable bit
- Handle the MMC DBLOCKSIZE field move

IR265772: MMC driver does not detect SDHC cards.
IR254201: Restructure MMC/SD driver for U8500 board according to the
block device framework in mainline U-Boot.
Changes to mmc framework:
- Multi Block Read support in mmc framework.
- Wrap Multi Block Write/Read to be able to adopt for large transaction.
- Removed incorrect check in EXT CSD for high capacity MMC.
- Corrected check for high capacity SD cards.
- Set MMC buswidth to 8, prio of using 4.
Known limitations/bugs in mmc framework:
- High capacity MMC, will likely not get the correct density.
- High speed is set, whether or not the host supports it or not.
board/st/u8500/mmc_utils:
IMPORTANT FOR DEVELOPERS:
- Removed unessary U-Boot commands which is already supported in
cmd_fat.
- mmc_read_cmd_file: Read command.txt into bootcmd env from FAT FS in
SD card.
- write_partition_block: Writes the MBR if it is not already written.
board/st/u8500/mmc_host[c.h]:
- Implements the entire MMC/SD host driver for the PL180 block.
- There is still room for optimization:
Increase CLK-speed.
Use high-speed for SD cards.
Is GPIO setup correctly for both cards an eMMC.
EarlyDrop support not fully tested.
Dynamically turn on voltage/clocks to SD, not always.
More...
Note:
- Increased read/write performance for eMMC, to around 5.4 MB/s for
sequential read/write. Earlier measurements was 3.5 MB/s for read and
2.6 MB/s for write.
