2 years agox86: Fix linking u-boot with ld.lld

x86: Fix linking u-boot with ld.lld

When linking the final u-boot binary with LLD, the following link errors
are seen:

ld.lld: error: can't create dynamic relocation R_386_32 against local
               symbol in readonly segment; recompile object files with
               -fPIC or pass '-Wl,-z,notext' to allow text relocations

>>> defined in arch/x86/cpu/start.o
>>> referenced by arch/x86/cpu/start.o:(.text.start+0x32)
[...]
>>> defined in arch/x86/cpu/start16.o
>>> referenced by arch/x86/cpu/start16.o:(.start16+0x1C)

According to Nick Desaulniers:

"This is a known difference between GNU and LLVM linkers; the GNU
 linkers permit relocations in readonly segments (making them not read
 only), LLVM does not (by default)."

Since U-Boot apparently seems to use relocations in readonly segments,
change the global linker flags to permit them when linking with LLD by
specifying '-z notext'.

arm: mvebu: Remove dummy BIN header arguments for SPL binary

U-Boot SPL binary does not read BIN header arguments, so passing some dummy
values 0000005b and 00000068 has no effect for U-Boot SPL code.

Probably these two values comes from old Marvell DDR training code which
was separated from U-Boot and used it for some configuration.

Seems that two 32-bit values were specified here to ensure SPL code
alignment to 128-bit boundary as it is required e.g. for A370 or AXP
processors. Main kwbimage header is 64-byte long which is aligned to
128-bit boundary. Optional kwbheader is 32-bit long, number of BIN header
arguments is stored in 32-bit number. So for alignment to 128-bit boundary
is needed 64-bit padding which exactly these two 32-bit dummy arguments
provided.

Now when mkimage correctly aligns start of executable code in BIN header to
128-bit boundary, there is no requirement to put dummy argument values into
kwbimage. So remove them.

mtd: mtdpart: Make mtdpart's _erase method sane

The _erase() method of the mtdpart driver, part_erase(), currently
implements offset shifting (for given mtdpart partition) in a weird way:
  1. part_erase() adds partition offset to block address
  2. parent driver's _erase() method is called
  3. parent driver's _erase() method calls mtd_erase_callback()
  4. mtd_erase_callback() subtracts partition offset from block address
     so that the callback function is given correct address
The problem here is that if the parent's driver does not call
mtd_erase_callback() in some scenario (this was recently a case for
spi_nor_erase(), which did not call mtd_erase_callback() at all), the
offset is not shifted back.

Moreover the code would be more readable if part_erase() not only added
partition offset before calling parent's _erase(), but also subtracted
it back afterwards. Currently the mtd_erase_callback() is expected to do
this subtracting since it does have to do it anyway.

Add the more steps to this procedure:
  5. mtd_erase_callback() adds partition offset to block address so that
     it returns the the erase_info structure members as it received them
  6. part_erase() subtracts partition offset from block address

This makes the code more logical and also prevents errors in case
parent's driver does not call mtd_erase_callback() for some reason.

(BTW, the purpose of mtd_erase_callback() in Linux is to inform the
 caller that it is done, since in Linux erasing is done asynchronously.
 We are abusing the purpose of mtd_erase_callback() in U-Boot for
 completely different purpose. The callback function itself has empty
 implementation in all cases in U-Boot.)
