      xlat: Fix compatibility between v1 and v2 · 03987d01
      Antonio Nino Diaz authored 
      

There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.

This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.

The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.

This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).

      Multi-console: Deprecate the `finish_console_register` macro · cc5859ca
      Soby Mathew authored 
      

The `finish_console_register` macro is used by the multi console
framework to register the `console_t` driver callbacks. It relied
on weak references to the `ldr` instruction to populate 0 to the
callback in case the driver has not defined the appropriate
function. Use of `ldr` instruction to load absolute address to a
reference makes the binary position dependant. These instructions
should be replaced with adrp/adr instruction for position independant
executable(PIE). But adrp/adr instructions don't work well with weak
references as described in GNU ld bugzilla issue 22589.

This patch defines a new version of `finish_console_register` macro
which can spcify which driver callbacks are valid and deprecates the
old one. If any of the argument is not specified, then the macro
populates 0 for that callback. Hence the functionality of the previous
deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define
is used to select the new variant of the macro and will be removed
once the deprecated variant is removed.

All the upstream console drivers have been migrated to use the new
macro in this patch.

NOTE: Platforms be aware that the new variant of the
`finish_console_register` should be used and the old variant is
deprecated.

      Makefile: Fix verbose builds on Windows · b5a0f4bd
      Antonio Nino Diaz authored 
      Commit <ee1ba6d4

> ("Makefile: Support totally quiet output with -s")
broke verbose (V=1) builds on Windows. This patch fixes it by adding
helpers to silence echo prints in a OS-dependent way.
