2015-02-09microblaze: Fix gd_t address which is placed at the end of BRAMMichal Simek
Setup gd from ASM to be availalbe for board_init_r. Setting it up in spl_board_init is too late when MALLOC is used. Space for gd is located behind MALLOC area at the end of BRAM. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2015-02-09arc: build libgcc in U-BootAlexey Brodkin
This way we may have very limited set of functions implemented so we save some space. Also it allows us to build U-Boot for any ARC core with the same one toolchain because we don't rely on pre-built libgcc. For example: * we may use little-endian toolchain but build U-Boot for ether endianess * we may use non-multilibbed uClibc toolchain but build U-Boot for whatever ARC CPU flavour that current GCC supports Private libgcc built from generic C implementation contributes only 144 bytes to .text section so we don't see significant degradation of size: --->8--- $ arc-linux-size u-boot.libgcc-prebuilt text data bss dec hex filename 222217 24912 214820 461949 70c7d u-boot.libgcc-prebuilt $ arc-linux-size u-boot.libgcc-private text data bss dec hex filename 222361 24912 214820 462093 70d0d u-boot.libgcc-private --->8--- Also I don't notice visible performance degradation compared to pre-built libgcc (where at least "*div*" functions are had-written in assembly) on typical operations of downloading 10Mb uImage over TFTP and bootm.

2015-02-09arc: move CPU flags selection to the main "config.mk"Alexey Brodkin
As a preparation to ARCv2 port submission we're moving CPU slection flags to a common location. Also it will allow us to have more flexible CPU specification, not only ISA version but CPU family as well checking CONFIG_ARC_CPU_xxx. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: hard-code CONFIG_ARCH_EARLY_INIT_R in asm/config.hAlexey Brodkin
Common arch_early_init_r() is used in "arc/lib/cpu.c" for all ARC boards so there's no sense in separate per-board definitions. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: hard-code CONFIG_SYS_GENERIC_BOARD into asm/config.hAlexey Brodkin
There're no other options for ARC except "generic board" so ther's no point to define CONFIG_SYS_GENERIC_BOARD per board. We now have it set fo all ARC boards. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: add selection of endianess in KconfigAlexey Brodkin
This change allows to keep board description clean and minimalistic. This is especially helpful if one board may house different CPUs with different features. It is applicable to both FPGA-based boards or those that have CPUs mounted on interchnagable daughter-boards. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: select cache settings via menuconfigAlexey Brodkin

2015-02-09arc: define and use PTAG AUX regs for MMUv3 onlyAlexey Brodkin
DC_PTAG and IC_PTAG registers only exist in MMUv3. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-02-09arc: add more flavours of ARC700 series CPUAlexey Brodkin
Now we may select a particular version of ARC700: * ARC750D or * ARC770D It allows more flexible (or more fine tuned) configuration of U-Boot. Before that change we relied on minimal configuration but now we may use specific features of each CPU. Moreover allows us to escape manual selection of options that exist in both CPUs but may have say different version like MMUv2 in ARC750D vs MMUv3 in ARC770D.
