6e6e4b2f73 sandbox: Allow to execute from RAM
With efi_loader, we may want to execute payloads from RAM. By default,
permissions on the RAM region don't allow us to execute from there though.

So let's change the default allocation scheme for RAM to also allow
execution from it. That way payloads that live in U-Boot RAM can be
directly executed.

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.

613185023f sandbox: Align RAM buffer to the machine page size
At present the sandbox RAM buffer is not aligned to any particular
address boundary. This makes the internal pointers somewhat random with
respect to the associated RAM buffer addresses.

Align the buffer to the page size of the machine to help with this. Note
that there is a header at the start of the allocated pointer. To avoid
returning a pointer which is not aligned to a page boundary, we waste
almost an entire page of memory for each allocation.

0797f7f0b7 ARM: tegra: reserve unmapped RAM so EFI doesn't use it
Tegra U-Boot ensures that board_get_usable_ram_top() never returns a value
over 4GB, since some peripherals can't access such addresses. However, on
systems with more than 2GB of RAM, RAM bank 1 does describe this extra
RAM, so that Linux (or whatever OS) can use it, subject to DMA
limitations. Since board_get_usable_ram_top() points at the top of RAM
bank 0, the memory locations describes by RAM bank 1 are not mapped by
U-Boot's MMU configuration, and so cannot be used for anything.

For some completely inexplicable reason, U-Boot's EFI support ignores the
value returned by board_get_usable_ram_top(), and EFI memory allocation
routines will return values above U-Boot's RAM top. This causes U-Boot to
crash when it accesses that RAM, since it isn't mapped by the MMU. One
use-case where this happens is TFTP download of a file on Jetson TX1
(p2371-2180).

This change explicitly tells the EFI code that this extra RAM should not
be used, thus avoiding the crash.

A previous attempt to make EFI honor board_get_usable_ram_top() was
rejected. So, this patch will need to be replicated for any board that
implements board_get_usable_ram_top().

2fd4284051 ARM: mach-mvebu: handle fall-back to UART boot
The bootROM in the Armada-38x (and similar) SoC has two modes for UART
boot. The first is when the normal boot media is blank (or otherwise
missing the kwb header). The second is when the boot sequence has been
interrupted with the magic byte sequence on the UART lines.

In the first mode the bootROM routine and error code register will
indicate that there was an error booting from the configured media in
bits 7:0. In the second mode there is no error to indicate but the boot
source is provided via bits 31:28.

Handle both situations so that kwboot can be used for both boot
strapping a blank board and for intercepting a regular boot sequence.

e599c4e7d8 sandbox: Build with -fPIC
