pc-bios/s390-ccw: Don't generate TEXTRELs

pc-bios/s390-ccw: Don't generate TEXTRELs

Commit 7cd50cbe4ca3 ("pc-bios/s390-ccw: Don't use __bss_start with the
"larl" instruction") introduced the address constant bss_start_literal
for __bss_start in the .text section, which introduced a relocation in
code (i.e. TEXTREL). The dedicated constant is required, as __bss_start
may not necessarily be aligned on a 2-byte boundary (see subject commit
for details).

Move the constant to the .data section to get rid of the relocation in
the .text section. Add the linker option -z text to prevent TEXTRELs to
get introduced in the future.

Note that the R_390_RELATIVE relocations are taken care of by function
glue() in include/hw/elf_ops.h.inc introduced by commit 5dce07e1cb67
("elf-loader: Provide the possibility to relocate s390 ELF files").

pc-bios/s390-ccw: Clarify alignment is in bytes

The assembler directive .align [1] has architecture-dependent behavior,
which may be ambiguous for the reader. Some architectures perform the
alignment in bytes, others in power of two. s390 does in bytes.

Use the directive .balign [2] instead, to clarify that the alignment
request is in bytes. No functional change.

pc-bios/s390-ccw: Don't use __bss_start with the "larl" instruction

start.S currently cannot be compiled with Clang 16 and binutils 2.40:

ld: start.o(.text+0x8): misaligned symbol `__bss_start' (0xc1e5) for
relocation R_390_PC32DBL

According to the built-in linker script of ld, the symbol __bss_start
can actually point *before* the .bss section and does not need to have
any alignment, so in certain situations (like when using the internal
assembler of Clang), the __bss_start symbol can indeed be unaligned
and thus it is not suitable for being used with the "larl" instruction
that needs an address that is at least aligned to halfwords.
The problem went unnoticed so far since binutils <= 2.39 did not
check the alignment, but starting with binutils 2.40, such unaligned
addresses are now refused.

Fix it by loading the address indirectly instead.

pc-bios/s390-ccw: Move the stack array into start.S

The stack array is only referenced from the start-up code (which is
shared between the s390-ccw.img and the s390-netboot.img), but it is
currently declared twice, once in main.c and once in netmain.c.
It makes more sense to declare this in start.S instead - which will
also be helpful in the next patch, since we need to mention the .bss
section in start.S in that patch.

While we're at it, let's also drop the huge alignment of the stack,
since there is no technical requirement for aligning it to page
boundaries.

pc-bios/s390-ccw: Provide space for initial stack frame in start.S

Providing the space of a stack frame is the duty of the caller,
so we should reserve 160 bytes before jumping into the main function.
Otherwise the main() function might write past the stack array.

While we're at it, add a proper STACK_SIZE macro for the stack size
instead of using magic numbers (this is also required for the following
patch).

start.S is currently indented with a mixture of spaces and tabs, which

and this is also what we are using in the assembler files in the

Also let's add an infinite loop into the assembly of disabled_wait() so
the caller doesn't need to take care of it.

Let's fix this once and forever by letting the BIOS zero the bss itself.
