21ebbafde8 test: dm: Add a test for PCI Enhanced Allocation
This test is built on top of the existing swap_case driver.  It adds EA
capability structure support to swap_case and uses that to map BARs.
BAR1 works as it used to, swapping upper/lower case.  BARs 2,4 map to a
couple of magic values.

001d1885f0 sandbox: Improve debugging in initcall_run_list()
At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:

  initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)

This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.

Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:

  initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)

Then you use can use grep to see which init call failed, e.g.:

   $ grep 0000000000048134 u-boot.map
   stdio_add_devices

Of course another option is to run it with a debugger such as gdb:

   $ gdb u-boot
   ...
   (gdb) br initcall.h:41
   Breakpoint 1 at 0x4db9d: initcall.h:41. (2 locations)

Note that two locations are reported, since this function is used in both
board_init_f() and board_init_r().

d0a9b82b75 regmap: fix regmap_read_poll_timeout warning about sandbox_timer_add_offset
When fixing sandbox test for regmap_read_poll_timeout(), the
sandbox_timer_add_offset was introduced but only defined in sandbox code
thus generating warnings when used out of sandbox :

include/regmap.h:289:2: note: in expansion of macro 'regmap_read_poll_timeout_test'
regmap_read_poll_timeout_test(map, addr, val, cond, sleep_us, \
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/spi/meson_spifc.c:169:8: note: in expansion of macro 'regmap_read_poll_timeout'
ret = regmap_read_poll_timeout(spifc->regmap, REG_SLAVE, data,
        ^~~~~~~~~~~~~~~~~~~~~~~~
drivers/spi/meson_spifc.c: In function 'meson_spifc_txrx':
include/regmap.h:277:4: warning: implicit declaration of function 'sandbox_timer_add_offset' [-Wimplicit-function-declaration]

This fix adds a timer_test_add_offset() only defined in sandbox, and
renames the previous sandbox_timer_add_offset() to it.

It is useful to be able to set the default log level from the command line
when running sandbox. Add a new -L command-line flag for this. The log
level is set using the enum log_level_t in log.h. At present a number must
be specified, e.g. -L7 for debug.

3fcb714758 sandbox: Fix setjmp/longjmp
In sandbox, longjmp returns to itself in an endless loop because
os_longjmp() calls into longjmp() which is provided by U-Boot which
again calls os_longjmp().

Setjmp on the other hand must not return because otherwise the
return freees up stack elements that we need during longjmp().

The only straight forward fix that doesn't involve nasty hacks I
could find is to directly link against the system setjmp/longjmp
implementations. That means we just provide the compiler with
hints that the symbol will be available and actually fill them
out with versions from libc.

This approach should be reasonably platform agnostic

428aa0ca56 sandbox: Enhance map_to_sysmem() to handle foreign pointers
At present map_sysmem() maps an address into the sandbox RAM buffer,
return a pointer, while map_to_sysmem() goes the other way.

The mapping is currently just 1:1 since a case was not found where a more
flexible mapping was needed. PCI does have a separate and more complex
mapping, but uses its own mechanism.

However this arrange cannot handle one important case, which is where a
test declares a stack variable and passes a pointer to it into a U-Boot
function which uses map_to_sysmem() to turn it into a address. Since the
pointer is not inside emulated DRAM, this will fail.

Add a mapping feature which can handle any such pointer, mapping it to a
simple tag value which can be passed around in U-Boot as an address.

3747bdbb2b arch: types.h: factor out fixed width typedefs to int-ll64.h
All architectures have the same definition for s8/16/32/64
and u8/16/32/64.

Factor out the duplicated code into <asm-generic/int-ll64.h>.

BTW, Linux unified the kernel space definition into int-ll64.h
a few years ago as you see in Linux commit 0c79a8e29b5f
("asm/types.h: Remove include/asm-generic/int-l64.h").

9865543ae6 Remove CONFIG_USE_STDINT
You do not need to use the typedefs provided by compiler.

Our compilers are either IPL32 or LP64.  Hence, U-Boot can/should
always use int-ll64.h typedefs like Linux kernel, whatever the
typedefs the compiler internally uses.
