f38753d2ef efi_selftest: fix HII tests
efi_st_printf() does not support format code %ld. Anyway the format code
for size_t would be %zu which isn't supported either.

We do not want any divisions to avoid invalid references to integer
arithmetic routines, cf.
https://gcc.gnu.org/onlinedocs/gccint/Integer-library-routines.html.

As a simple remedy remove the noisy messages from the output.
They are not relevant for automated testing.

c9bfb22296 efi_loader: Initial HII database protocols
This patch provides enough implementation of the following protocols to
run EDKII's Shell.efi and UEFI SCT:

  * EfiHiiDatabaseProtocol
  * EfiHiiStringProtocol

Not implemented are:
  * ExportPackageLists()
  * RegisterPackageNotify()/UnregisterPackageNotify()
  * SetKeyboardLayout() (i.e. *current* keyboard layout)

HII database protocol in this patch series can handle only:
  * GUID package
  * string package
  * keyboard layout package
  (The other packages, except Device path package, will be necessary
   for interactive and graphical UI.)

eefb790e90 efi_loader: fix GetNextVariableName
Our current implementation of GetNextVariableName() first collects all EFI
variables. If none is found at all hexport_r() returns a zero length string
terminated by \0 and the value 1 as number of bytes in the returned buffer.

In this case GetNextVariableName() has to return EFI_NOT_FOUND.

a comparison between RAM top and RAM start that was not known at the time
when the patch of commit 49759743bf ("efi_loader: eliminate sandbox

The sandbox uses an address space that is only relevant in the sandbox
context. We have to map ram_top from the sandbox address space to the
physical address space before using it in the EFI subsystem.

47870afab9 initcall: Move to inline function
The board_r init function was complaining that we are looping through
an array, calling all our tiny init stubs sequentially via indirect
function calls (which can't be speculated, so they are slow).

The solution to that is pretty easy though. All we need to do is inline
the function that loops through the functions and the compiler will
automatically convert almost all indirect calls into direct inlined code.

With this patch, the overall code size drops (by 40 bytes on riscv64)
and boot time should become measurably faster for every target.

Only first previously deleted entry was recognized, leading hsearch_r
to think that there was no previously deleted entry. It then conluded
that a free entry was found, even if there were no free entries and it
overwrote a random entry.

This patch makes sure all deleted or free entries are always found and
also introduces constants for the 0 and -1 numbers. Unit tests to excersise a
simple hash table usage and catch the corruption were added.

To trash your environment, simply run this loop:

4cc8af8037 lib: lmb: extend lmb for checks at load time
This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.

lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.

lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.

Added test for these new functions.
