The raw_write_sctlr_current() cannot be used in mmu_disable() because
it pushes some registers to cached stack, and then just after cache

The framebuffer structure lives in the coreboot tables. Those
tables have a checksum calculation applied over all the entries.
Therefore, one shouldnot be modifying fields within the coreboot
table entries because the calculated checksum would be wrong.

1. keep functions and objects used entirely within mmu.c as static.
2. DMA region finding needs to terminate. Therefore, the next address
to be attempted needs to be less then the current end address.
3. Ensure mmu_ranges passed to mmu_init_ranges_from_sysinfo() has

What this change does:
1) Initialize limited page tables as soon as we jump into libpayload. Basically
two ranges are initialized. One is for the BASE_ADDRESS and other is for the
coreboot_tables. With page tables initialized and MMU enabled, we jump into
code to parse coreboot tables.
2) Once coreboot tables are parsed and we have complete picture of the memory,
we perform a complete page table initialzation and enable MMU and then jump to
payload.
Additionally, we also:
1) Initialize DMA memory on our own depending upon the memory map. It ensures
that the DMA buffer is placed in 32-bit memory.

provide read_current and write_current assembly macros. These are included in
arch/lib_helpers.h under the __ASSEMBLY__ macro condition. This is done to allow

timer_raw_value must return the number of CPU ticks, and not
the time obtained by dividing the ticks by the CPU frequency.
The CPU counter is increased at every 2 CPU clocks
and therfore the number of ticks will be the counter value
multiplied by 2.

The default string functions work with multiple of 4 bytes
(sizeof(unsinged long)); MIPS will use LW/SW instructions
for these operations and if the source and destination
addresses are not aligned it will trigger an exception.
Therefore, this implementation does all data access operations
per byte, because there is no guarantee that the provided
strings are properly aligned.

There are three instances of coreboot.c in libpayload. for x86, arm
and arm64 architectures. The arm and arm64 instances are exactly the
same. The differences with the x86 instance are as follows:
- a very slightly different set of coreboot table tags is parsed (one
tag added and two removed)
- instead of checking a fixed address if it contains the coreboot
table, the x86 version iterates over two address ranges.
This patch refactors the module, leaving architecture specific
processing in arch subdirectories and moving the common code into
libc.

For memalign() requests the current allocator keeps metadata
about each chunk of aligned memory that copmrises the size
requested. For large allocations relative to the alignment
this can cause significant metadata overhead. Instead, consider
all memalign() requests whose size meets or exceeds 1KiB or
alignment that meets or exceeds 1KiB large requests.
These requests are handled specially to only allocate
the amount of memory required for the size and alignment
constraints by not allocating any metadata as the whole region

definitions.

Add OpenBSD's header-only implementation of some
basic data structures, imported from
src/sys/sys/queue.h, revision 1.38
(all whitespace errors kept verbatim)
Unlike home-grown solutions they likely handle
all corner cases correctly from the start and
unlike Linux's solution it's properly documented
(see OpenBSD's LIST_INIT(3)) and also BSD-l.

The serial driver hangs in cases when FIFO has more than single word to be
processed. Easiest way to reproduce is to paste a string of greater than 4
characters in cli.
Clearing the RXSTALE interrupt without draining all the characters from FIFO
leads to the issue as the driver is dependent on msm_boot_uart_dm_read
function to reinitialize for next transfer.
Logically the driver is organized in such a manner that next transfer never
gets initiated till rx_data_read < total_rx_data. Clearing the RXSTALE without
consideration of total number of characters (or words) unprocessed makes the
msm_boot_uart_dm_read to return on the first if conditional. Thus the driver is
stuck forever.
A quick fix is to avoid clearing the stale interrupt. Reset is handled whenever
a new transfer is initialized in msm_boot_uart_dm_init_rx_transfer.

Init curses as late as possible and tear them down early. There are possible
error outs after that and they don't look nice with curses initialized.
