19ea4678ca Use uint64_t for time types
Unfortunately 'unsigned long long' and 'uint64_t' are not necessarily
compatible on 64-bit machines. Use the correct typedef instead of
writing the supposed type out in full.

4166ecb247 Add some standard headers external code might need
inttypes.h defines format specifiers for printf which work with data types of
particular sizes. stdlib.h is currently just a passthrough to malloc.h which
has declarations of the various *alloc functions.

Add the required #define to common.h so that these printf format specifiers
will be made available.

5038d7f189 ppc: Zap Hymod board
Remove this board as this is the only one last user of eeprom_probe(),
which is pretty non-standard stuff.

This patch also removes all the PHP, SQL and CSS stuff from U-Boot,
which probably makes U-Boot a bit less IoT ;-)

1fb4dab2a1 arm:reset: call the reset_misc() before the cpu reset
On an Odroid U3 board, the SOC is unable to reset the eMMC card
in the DWMMC mode by the cpu software reset. Manual reset of the card
by switching proper gpio pin - fixes this issue.

Such solution needs to add a call to pre reset function.
This is done by the reset_misc() function, which is called before reset_cpu().
The function reset_misc() is a weak function.

709ea543b9 stdio: Pass device pointer to stdio methods
At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.

For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.

Instead, add a stdio_dev pointer to each of the stdio member functions.

Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

20f86a0aea sandbox: Deal with conflicting getenv() for SDL
Unfortunately SDL requires getenv() to operate, since it wants to figure out
the display type. U-Boot has its own getenv() and they conflict. As a
work-around use #define to resolve the conflict.

A better but more complex solution might be to rename some U-Boot symbols
at link time. SDL audio is not functional at present, likely due to a related
issue.

Note: Vic Yank wrote a script for this, filed in crbug.com/271125.

58dac32764 powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260
Before this commit, CONFIG_MPC8260 and CONFIG_8260
were used mixed-up.

All boards with mpc8260 cpu defined both of them:
  - CONFIG_MPC8260 was defined in board config headers

  - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk

We do not need to have both of them.
This commit keeps only CONFIG_MPC8260.

This commit does:
 - Delete CONFIG_8260 and CONFIG_MPC8260 definition
   in config headers and include/common.h
 - Rename CONFIG_8260 to CONFIG_MPC8260
    in arch/powerpc/cpu/mpc8260/config.mk.

ba6a169811 ARM: add SMP support for non-secure switch
Currently the non-secure switch is only done for the boot processor.
To enable full SMP support, we have to switch all secondary cores
into non-secure state also.

So we add an entry point for secondary CPUs coming out of low-power
state and make sure we put them into WFI again after having switched
to non-secure state.
For this we acknowledge and EOI the wake-up IPI, then go into WFI.
Once being kicked out of it later, we sanity check that the start
address has actually been changed (since another attempt to switch
to non-secure would block the core) and jump to the new address.

The actual CPU kick is done by sending an inter-processor interrupt
via the GIC to all CPU interfaces except the requesting processor.
The secondary cores will then setup their respective GIC CPU
interface.
While this approach is pretty universal across several ARMv7 boards,
we make this function weak in case someone needs to tweak this for
a specific board.

The way of setting the secondary's start address is board specific,
but mostly different only in the actual SMP pen address, so we also
provide a weak default implementation and just depend on the proper
address to be set in the config file.

063ae006ae main: Separate out the two abortboot() functions
There are two implementations of abortboot(). Turn these into two separate
functions, and create a single abortboot() which calls either one or the
other.

Also it seems that nothing uses abortboot() outside main, so make it static.

At this point there is no further use of CONFIG_MENU in main.c.

781adb5710 sandbox: Provide a way to map from host RAM to U-Boot RAM
In many cases, pointers to memory are passed around, and these pointers
refer to U-Boot memory, not host memory. This in itself is not a
problem.

However, in a few places, we cast that pointer back to a ulong (being
a U-Boot memory address). It is possible to convert many of these cases
to avoid this. However there are data structures (e.g. struct
bootm_headers) which use pointers. We could with a lot of effort adjust
the structs and all code that uses them to use ulong instead of pointers.

This seems like an unacceptable cost, since our objective with sandbox
is to minimise the impact on U-Boot code while maximising the features
available to sandbox.

Therefore, create a map_to_sysmem() function which converts from a
pointer to a U-Boot address. This can be used sparingly when needed.

4213fc2913 sandbox: Add un/map_sysmen() to deal with sandbox's ram_buf
Sandbox doesn't actually provide U-Boot access to the machine's physical
memory. Instead it provides a RAM buffer of configurable size, and all
memory accesses are within that buffer. Sandbox memory starts at 0 and
is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
might produce unpredictable results in the event of an error, and would
expose the host machine's memory architecture to the sandbox U-Boot.

Most U-Boot functions assume that they can just access memory at given
address. For sandbox this is not true.

Add a map_sysmem() call which converts a U-Boot address to a system
address. In most cases this is a NOP, but for sandbox it returns a
pointer to that memory inside the RAM buffer.

To get a U-Boot feature to work correctly within sandbox, you should call
map_sysmem() to get a pointer to the address, and then use that address for
any U-Boot memory accesses.

eef1cf2d5c include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives.  Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h.  They come with 'const' added for some swab functions, so
fix those up, too:

include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).

We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token

powerpc sparse builds yield:

include/common.h:356:22: error: marked inline, but without a definition

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'

295d3942b8 Add board_pre_console_putc to deal with early console output
This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.

A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.

The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

bbb0b128c3 fdt: Add support for embedded device tree (CONFIG_OF_EMBED)
This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.

The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.

This commit contains my entry for the ugliest Makefile / shell interaction

d29d17d7ba powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driver
Unified DDR driver is maintained for better performance, robustness and bug
fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of
overall improvement. It requires changes for board files to customize
platform-dependent parameters.

To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx
in the header file. No more boards will be accepted without such definition.

Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1
and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

21726a7afc Add assert() for debug assertions
assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined.
This is useful when a condition is an error but a board reset is unlikely
to fix it, so it is better to soldier on in hope. Assertion failures should
be caught during development/test.

It turns out that assert() is defined separately in a few places in U-Boot
with various meanings. This patch cleans up some of these.

155cfb5ef1 common: fix behavior of ROUND macro when input is already rounded
Currently when you call ROUND with a value that is already a
multiple of the second parameter it will return a value that is
one multiple larger, instead of returning the value passed in.

There are only two types of usage of ROUND currently, one in
various config files to round CONFIG_SYS_MALLOC_LEN to a multiple
of 4096 bytes.  The other in cmd_sf.c where the incorrect behavior
of ROUND is worked around be subtracting one from the length argument
before passing it to ROUND.

This patch fixes ROUND and removes the workaround from cmd_sf.  It
also results in all of the malloc pools that use ROUND to compute
their size shrinking by 4KB.

	- Invalidate D-cache range
	- Flush(clean & invalidate) entire D-cache
	- Flush D-cache range
- I-cache operations supported:
	- Invalidate entire I-cache

- Add maintenance functions for TLB, branch predictor array etc.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
