* libfdt: Introduce new ARCH_FIXUP_FDT optionMichal Simek2016-07-31-0/+2
| | | | | | | | | | Add new Kconfig option to disable arch_fixup_fdt() calls for cases where U-Boot shouldn't update memory setup in DTB file. One example of usage of this option is to boot OS with different memory setup than U-Boot use. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Acked-by: Simon Glass <sjg@chromium.org>
* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-17/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

* MIPS: Make CONFIG_SYS_DCACHE_LINE_SIZE int, not hexPaul Burton2016-06-10-1/+1
| | | | | | | | | For consistency with the other cache-related Kconfig entries & the values actually set by boards, make CONFIG_SYS_DCACHE_LINE_SIZE an int entry instead of a hex entry.

| | | | | | | | | | Commit fb64cda57998 ("MIPS: Abstract cache op loops with a macro") accidentally modified invalidate_dcache_range to operate on the L1 Icache instead of the Dcache.

* MIPS: Abstract cache op loops with a macroPaul Burton2016-05-31-41/+18
| | | | | | | | | | | The various cache maintenance routines perform a number of loops over cache lines. Rather than duplicate the code for performing such loops, abstract it out into a new cache_loop macro which performs an arbitrary number of cache ops on a range of addresses. This reduces duplication in the existing L1 cache maintenance code & will allow for not adding further duplication when introducing L2 cache support. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* MIPS: Split I & D cache line size configPaul Burton2016-05-31-20/+25
| | | | | | | | | | | | Allow L1 Icache & L1 Dcache line size to be specified separately, since there's no architectural mandate that they be the same. The [id]cache_line_size functions are tidied up to take advantage of the fact that the Kconfig entries are always present to simply check them for zero rather than needing to #ifdef on their presence.

* MIPS: Move cache sizes to KconfigPaul Burton2016-05-31-4/+32
| | | | | | | | | | | | Move details of the L1 cache line sizes & total sizes into Kconfig, defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is introduced to allow platforms to select auto-detection of cache sizes, and it defaults to being enabled if none of the cache sizes are set by the configuration (ie. sizes are all the default 0), and code is adjusted to #ifdef on that rather than on the definition of the sizes (which will always be defined even if 0).

* MIPS: remove dead code from asm/u-boot-mips.hDaniel Schwierzeck2016-05-31-18/+3

* malta: Allow MIPS64 buildsPaul Burton2016-05-31-0/+3

* MIPS: Use CPHYSADDR to implement mips32 virt_to_physPaul Burton2016-05-31-4/+1
| | | | | | | | | | | | | | | | | | Use CPHYSADDR to implement the virt_to_phys function for converting from a virtual to a physical address for MIPS32, much as is already done for MIPS64. This allows for virt_to_phys to work regardless of whether the address being translated is in kseg0 or kseg1, unlike the previous subtraction based approach which only worked for addresses in kseg0. This allows for drivers to provide an address to virt_to_phys without needing to manually ensure that kseg1 addresses are converted to equivalent kseg0 addresses first.

| | | | | | | | | | | Make use of device model & device tree to probe the UART driver.

* MIPS: Support for targetting MIPSr6Paul Burton2016-05-21-6/+30
| | | | | | | | | | | 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: Simplify CONFIG_SYS_CPU valuesPaul Burton2016-05-21-2/+2
| | | | | | | | | | | | Rather than having the values for CONFIG_SYS_CPU depend upon each architecture revision, have them depend upon the more general CONFIG_CPU_MIPS32 & CONFIG_CPU_MIPS64 which in turn depend upon the architecture revisions. This is done in preparation for adding MIPSr6 support, which would otherwise need to introduce new cases here. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* MIPS: Use unchecked immediate addition/subtractionPaul Burton2016-05-21-11/+13
| | | | | | | | | | | | In MIPS assembly there have historically been 2 variants of immediate addition - the standard "addi" which traps if an overflow occurs, and the unchecked "addiu" which does not trap on overflow. In release 6 of the MIPS architecture the trapping variants of immediate addition & subtraction have been removed. In preparation for supporting MIPSr6, stop using the trapping instructions from assembly & switch to their unchecked variants. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
