Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.
Also, use the generic definition mod_arch_specific where possible.
To this end, I've defined three new config bools:
(*) HAVE_MOD_ARCH_SPECIFIC
Arches define this if they don't want to use the empty generic
mod_arch_specific struct.
(*) MODULES_USE_ELF_RELA
Arches define this if their modules can contain RELA records. This causes
the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
defined by the arch rather than have the core emit an error message.
(*) MODULES_USE_ELF_REL
Arches define this if their modules can contain REL records. This causes
the Elf_Rel mapping to be emitted and allows apply_relocate() to be
defined by the arch rather than have the core emit an error message.
Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.
With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.
Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

AVR32 is a high-performance 32-bit RISC microprocessor core,
|
|
designed for cost-sensitive embedded applications, with particular
|
|
emphasis on low power consumption and high code density.
|
|
|

The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
|
|
It offers versatile peripherals, such as ethernet, usb device, usb host etc.
|
|
|
|
The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
|
|
Device (PD).
|
|
|
|
Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
|
|
mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
|
|
will cover even the most exceptional need of memory bandwidth. Together with the onboard
|
|
video decoder the board is ready for video processing.

Merisc is the family name for a range of AVR32-based boards.
|
|
|
|
The boards are designed to be used in a man-machine
|
|
interfacing environment, utilizing a touch-based graphical
|
|
user interface. They host a vast range of I/O peripherals as
|
|
well as a large SDRAM & Flash memory bank.
