i2c: mxc: refactor i2c driver and support dm
1. Introduce a new structure `struct mxc_i2c_bus`, this structure will
used for non-DM and DM.
2. Remove `struct mxc_i2c_regs` structure, but use register offset to access
registers based on `base` entry of `struct mxc_i2c_bus`.
3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform
flags. A new flag is introduced, I2C_QUIRK_FLAG.
4. Most functions use `struct mxc_i2c_bus` as one of the parameters.
Make most functions common to DM and non-DM, try to avoid duplicated code.
5. Support DM, but pinctrl is not included. Pinmux setting is still set
by setup_i2c, but we do not need bus_i2c_init for DM.
6. struct i2c_parms and struct sram_data are removed.
7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist
paramter of bus_i2c_init is modified to i2c index. Add new prototype
i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for
DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus.
Board file take the responsibility to implement this function, like this:
"
int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus)
{
if (i2c_bus->index == 0)
force_bus_idle(i2c_pads_info0);
else if (i2c_bus->index == 1)
force_bus_idle(i2c_pads_info1);
else
xxxxxx
}
"
8. Introduce a weak function, enable_i2c_clk

which means that if we have an interrupt endpoint at endpoint 1 with one

with the same ed linked into both the periodic and async lists, which is
not good (tm).

tegra124: Add PSCI support for Tegra124
This is based on Thierry Reding's work and uses Ian Campell's
preparatory patches. It comes with full support for CPU_ON/OFF PSCI
services. The algorithm used in this version for turning CPUs on and
off was proposed by Peter De Schrijver and Thierry Reding in
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/210881. It
consists of first enabling CPU1..3 via the PMC, just to powergate them
again with the help of the Flow Controller. Once the Flow Controller is
in place, we can leave the PMC alone while processing CPU_ON and CPU_OFF
PSCI requests.

virt-dt: Allow reservation of secure region when in a RAM carveout
In this case the secure code lives in RAM, and hence the memory node in
the device tree needs to be adjusted. This avoids that the OS will map
and possibly access the reservation.
Add support for setting CONFIG_ARMV7_SECURE_RESERVE_SIZE to carve out
such a region. We only support cutting off memory from the beginning or
the end of a RAM bank as we do not want to increase their number (which
would happen if punching a hole) for simplicity reasons

ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalization
As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr
serve essentially the same purpose. Roughly, if a command takes a load
address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default
if the command-line does not specify the address. Different U-Boot
commands are inconsistent re: which of the two default values they use.
As such, set the two to the same value, and move the logic that does this
into tegra-common-post.h so it's not duplicated. A number of other non-
Tegra boards do this too.
The values chosen for these macros are no longer consistent with anything
in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r
to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default
kernel load address, whereas newer scripts and features tend to use
$kernel_addr_r, along with other variables for other purposes such as
DTBs and initrds. Hence, it's logical they should share the same value.
I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR
have different values. This would guarantee no interference if a script
used the two variables for different purposes. However, that scenario is
unlikely given the semantic meaning associated with the two variables.
The lowest available value is 0x90200000; see comments for
MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However,
that value would be problematic for a script that loaded a raw zImage to
$loadaddr, since it's more than 128MB beyond the start of SDRAM, which
would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do
that.
The only potential fallout I could foresee from this patch is if someone
has a script that loads the kernel to $loadaddr, but some other file
(DTB, initrd) to a hard-coded address that the new value of $loadaddr
interferes with. This seems unlikely. A user should not do that; they
should either hard-code all load addresses, or use U-Boot-supplied
variables for all load addresses. Equally, any fallout due to this change
is trivial to fix; simply modify the load addresses in that script.

ppc4xx: Remove sc3 board
As this board seems to be unmaintained for quite some time, and its
not moved to the generic board ingrastructure, lets remove it.
This will also enable us to remove the CONFIG_AUTOBOOT_DELAY_STR2
and CONFIG_AUTOBOOT_STOP_STR2 macros, as this sc3 board is the
only one using one of this macros. A removal patch will follow
soon.

Fix broken verify functionality in crc32 command
Introduced in change
d20a40de9db07de1f1f06a79a4da1cdda5379b75
"Roll crc32 into hash infrastructure"
The crc32 command with no -v expects an optional 3rd argument to be an
address to store the result in. With the -v switch, the last argument
is a crc, not an address. In the case where -v is set, we should set the
HASH_FLAG_ENV flag since that will first look for the value to be a
digest value, which matches the expected API for the crc32 command.
