We've decided that it is generally okay for coreboot to expect unaligned
accesses to work. Trying to find all instances of unaligned access
opportunities and working around them in software would be an
unsustainable whack-a-mole contest. Instead, architectures and boards
need to make sure they conform to this, which on ARM and ARM64 requires
setting up paging early in the bootblock.
Other architectures (x86, ARM64, MIPS) already generate code in this
manner. ARM still had an -mno-unaligned-access flag hanging around that
has been copied so many times its initial origin was lost in time
(probably U-Boot). Let's remove it for consistency between architectures
and to improve code generation.

TEST=Booted Jerry and Blaze. Looked at the disassembly for
timestamp_sync() and confirmed that it only gives you half as much eye
cancer as before (GCC still somehow insists on byte accesses when
zeroing fields which is very odd, but at least that terrible AND/OR mess
is gone). Measured a boot time increase of about 11ms on Jerry (mostly
faster timestamp and CBFS accesses). Could not test Storm because
despite our claimed abundance of test devices, every time I get one of
them it magically disappears again in less than a week.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

The AS3277 RTC code seems to closely follow the corresponding Linux
driver. Unfortunately, while coreboot (and even other parts of Linux,
like mktime()) directly follows the standard IBM PC RTC time
representation (except for the BCD part), Linux' struct rtc_time decided
to use 0-based (instead of 1-based) months instead.

We want a reset signal to last 200us. The length of a reset signal is
represented by BIT0~BIT16 in DDR_PUBL_PTR2. When DDR memory runs at
667MHz, the calculated value for the reset signal is 0x20850, which is
bigger than the maximum value that can be described with 17 bits
(0x1ffff). As a result, the memory controller only sees 0x850, which
generates a 3.5us reset cycle instead, which violates the standard and
negatively impacts memory stability.
So instead, we now set it to the maximum value (0x1ffff) to prevent this
overflow, resulting in a reset signal of 196us for 667MHz DDR memory.

Read the TZBSP blob from CBFS and run it. A side effect of the blob
execution is switching the processor into User mode.
Starting TZBSP requires processor running in Supervisor mode, TZBSP
code is compiled for ARM. Coreboot is executing in System mode and is
compiled for Thumb. An assembler wrapper switches the execution mode
and interfaces between Thumb and ARM modes.

This moves PMIC_BUS from each mainboard's board.h file to a per-
mainboard Kconfig variable. To prevent humans from forgetting to
set a valid value, an invalid default is set in the rk3288 Kconfig
and checked in rk808.c so that compilation will fail if the mainboard
Kconfig does not override it.
Originally, PMIC_BUS was only used by mainboard code as an argument
to RK808 PMIC functions. To conform to the generic RTC API, however,
the RK808 code needs to have the bus number globally defined somewhere
since the rtc_get() and rtc_set() functions don't take any args.
Since CONFIG_PMIC_BUS is globally visible, we no longer need to pass
bus number to the PMIC functions.
