CONFIG_TARGET_FOO is only used in board/sunxi/Makefile to select the
dram config for sun5i and sun7i boards and in board/sunxi/gmac.c for some
special handling of the bananapi/bananapro (both sun7i), iow it is not used
at all on any sun4i, sun6i and sun8i boards so lets get rid of it there.

Currently we've separate detailed dram settings for all sun4i boards, this

While working on adding more boards I noticed that we lack a config for
the 512M cubieboard, and that some of the new boards which I want to add also
have 512M and 1G variants, rather then adding 2 defconfig's for all of these,
lets switch the exising boards which have both a 512M and 1024M variant over
to the sun4i dram autoconfig code.

This also drops the foo_RAMSIZE_defconfig variants of boards where we currently
have 2 separate configs already.

Note:
1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with
a value other then its default for now, but we need this to be configurable
to support some new boards with auto dram config.

2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match
the defaults, this is done to make it more clear what values are used for a
certain board.

This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G
variants, the dram autoconfig code has also been tested on a 512M mk802
(a defconfig for the mk802 is added in a later patch).

We do not use the axp209 interrupt, and at least in my mini-x (which does not
have a power button) the pwr-button pin and the irq pin are soldered together,
so if the axp209 keeps it irq asserted too long it will see a 10s pwr-button
press and hard power off the board, disabling the irqs fixes this.

While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module
I noticed that the screen flickered. This is caused by the lcd display clk
phase reg value being set to 0, where it should be 1 in this setup.

This commit adds a Kconfig option for the lcd display clk phase, so that we
can set it per board. This defaults to 1, because looking at all the fex
files in sunxi-boards, that is by far the most used value.

This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the
default of 1 with 0, as that is the correct value for those tablets, this
keeps the register settings the same as before this commit.

The Olinuxino-A13 defconfigs are not updated, changing the register setting
for these boards from 0 to 1, this is intentional.

2 recent sunxi changes have removed the usage of lowlevel_init by moving some
code around and then setting CONFIG_SKIP_LOWLEVEL_INIT.
This is problematic for 2 reasons:

1) It does not just stop s_init from being called, it also stops
cpu_init_cp15 from getting called, which is undesirable.

2) We want u-boot.bin to be usable standalone, without SPL, some people e.g.
use an upstream u-boot.bin together with Allwinner's boot0 loader. So
u-boot.bin must (re)initialize the gpios, timer, etc.

This commit restores the lowlevel_init / s_init usage, while keeping the
changes to no longer use the global-data (gd) struct in the SPL.

Wider bus widths (larger than default 1 bit) appeared in MMC standard
version 4.0. So, for MMC cards of any earlier version trying to change
the bus width (including ext_csd comparison) does not make any sense.
It may work incorrectly and at least cause unnecessary timeouts.
So, just skip the entire bus width related activity for earlier versions.

Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
Tested-by: Alexey Brodkin <abrodkin@synopsys.com>

If all the commands switching an MMC card to 4- or 8-bit bus width fail,
and the bus width for the controller and the driver is still set
to default 1 bit, there is no need to send one more command to switch
the card to 1-bit bus width. Also, if the card or host controller do not
support wider bus widths, there is no need to send a switch command at all.

However, if one of switch commands succeeds, but the subsequent ext_csd
fields comparison fails, the card should be switched to some other bus width
(next in the list for the loop), or to default 1-bit bus width as a last
resort. That's why it would be incorrect to just remove the 1-bit bus width
case from the list, it should still be processed in some cases.

This adds an API to do hardware partitioning on eMMC devices. The
new mmc_hwpart_config() function does the partitioning in one go.
As the different attributes and partitioning options on eMMC may
be interdependent validation has to be done based on the complete
partitioning configuration. The function accepts three modes:

- MMC_HWPART_CONF_CHECK: just validates that the configuration
  is valid.
- MMC_HWPART_CONF_SET: validates and sets all the fields in
  EXT_CSD but without setting the "partitioning completed" bit,
  and thus is reversible.
- MMC_HWPART_CONF_COMPLETE: does everything and is thus not
  reversible.

The mmc_startup() function uses the ext_csd data even if reading it
from the mmc device failed. This bug was introduced in commit
bc897b1d. We now bail out if
reading it fails, this should not be a problem as ext_csd was
introduced in MMC 4.0 and this code is conditional on MMC >= 4.0.

The eMMC spec says that partitioning is only effective after the
PARTITION_SETTING_COMPLETED is set in EXT_CSD (and a power cycle was done,
but that we cannot know). Thus the partition sizes and attributes should
be ignored when that bit is not set, otherwise the various capacities
are not coherent (e.g., the user data capacity will be that of the
unpartitioned device while partition sizes would be non-zero).

Prescence of non-zero partitioning data is nevertheless still used to
activate the high-capacity size definitions (EXT_CSD_ERASE_GROUP_DEF)
as it is necessary to set that to write any of the partitioning fields
in EXT_CSD, so having partitioning data means someone previously
activated that and we should keep it activated.

The erase_grp_size in struct mmc is to be a size in 512-byte sectors

The eMMC spec mandates that the high-capacity group size definitions
should be enabled when the device is partitioned (by setting
ERASE_GROUP_DEF in EXT_CSD). The current test to determine when this is
required misses a few cases. In particular a device may have been
partitioned without setting the enhanced attribute on any partition
or partitioning may be completed without creating any extra partitions.

This change moves the code to set ERASE_GROUP_DEF to after reading
all partition information. It is also enabled when
PARTITIONING_SETTING_COMPLETED is set as it is necessary to enable
ERASE_GROUP_DEF before setting that bit, so it means that the user
previously switched to the high capacity definitions.
