* MIPS: add tune for MIPS 34kcDaniel Schwierzeck2016-05-31-0/+1
| | | | | | Add tune Kconfig option for MIPS 34kc. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* mips: Allow overriding start.S in SPLMarek Vasut2016-05-26-0/+6
| | | | | | | | | | Certain chips, like the JZ47xx, have extreme size constraints on the SPL size and require custom start.S . Allow overriding the start.S the same way ARM MXS does it.

* MIPS: Support for targetting MIPSr6Paul Burton2016-05-21-0/+2
| | | | | | | | | | | Add support for targetting MIPS32r6 & MIPS64r6 systems, in the same way that we currently select release 1 or release 2 targets. MIPSr6 is not entirely backwards compatible with earlier releases of the architecture. Some instructions are encoded differently, some are removed, some are reused, so it is not practical to run U-Boot built for earlier revisions on a MIPSr6 system. Update their Kconfig help text to reflect that. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

* mips: add base support for QCA/Atheros ath79 SOCsWills Wang2016-05-21-0/+1
| | | | | | | This patch add some common code for QCA/Atheros ath79 SOCs such as DDR tuning, chip reset and CPU detection. Signed-off-by: Wills Wang <wills.wang@live.com>
* MIPS: initial infrastructure for Microchip PIC32 architecturePurna Chandra Mandal2016-02-01-0/+1
| | | | | | | | | Create initial directory, Kconfigs needed for PIC32 architecture support. Also add PIC32 specific register definition required for drivers.

* MIPS: sync I/O related header files with linux-4.4Daniel Schwierzeck2016-01-16-1/+4
| | | | | | | | | | | | | Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces. All files in that directory can be overwritten by a SoC/machine. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: Kconfig: optimize gcc -march and -mtune setupDaniel Schwierzeck2016-01-16-0/+13
| | | | | | | | Move setup of -march to arch/mips/Makefile and follow the design on ARM. Also add a possibility to chose specific CPU tune options. Signed-off-by: Wills Wang <wills.wang@live.com> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: Kconfig: refactor machine setupDaniel Schwierzeck2016-01-16-1/+6
| | | | | | | | Refactor machine setup like it is done on ARM. While on it, also support "include <mach/file.h" for machine specific header files. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: unify CPU code in arch/mips/cpu/Daniel Schwierzeck2015-01-30-4/+2
| | | | | | | | | Unify and move code in arch/mips/cpu/mips[32|64]/ to arch/mips/cpu/. The CPU specific config.mk files need to remain until CONFIG_STANDALONE_LOAD_ADDR is converted to a global Kconfig symbol.

* MIPS: move au1x00 SoC code to arch/mips/mach-au1x00Daniel Schwierzeck2015-01-30-0/+2
| | | | | | | | | | Move all au1x00 code out of arch/mips/cpu/mips32 to allow unification of CPU code in a later patch. The reorganization of the SoC specific header files will be done in a later patch series. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Cc: Paul Burton <paul.burton@imgtec.com>
* MIPS: replace $(CPU) with Kconfig symbolsDaniel Schwierzeck2015-01-21-2/+4
| | | | | | | Conditionally set head-y and lib-y with boolean Kconfig symbols for selected CPU. This deprecates the usage of the $(CPU) variable. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck2014-12-08-0/+8
Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.
