* MIPS: drop redundant debug_ll_outhexw macro definesAntony Pavlov2017-01-101-32/+0
| | | | | | | | | | | | The debug_ll_outhexw macro has no dependency on UART model so we can remove it from UART-dependent header files (debug_ll_ns16550.h and mach-ath79/.../debug_ll.h). On the other hand the only debug_ll_outhexw user is MIPS nmon monitor so we can move the debug_ll_outhexw macro to pbl_nmon.h.

* MIPS: ath79: pbl: import hornet_1_1_war routine from U-Boot_modAntony Pavlov2016-02-261-0/+43
| | | | | | | | | | | | | | | | U-Boot_mod is a popular bootloader for Atheros AR93xx chips, please see https://github.com/pepe2k/u-boot_mod for details. It's reasonable to import some lowlevel AR9331 initialization code from U-Boot_mod. AR9331 (Hornet) 1.1 currently needs an additional reset at 1st boot. This patch imports necessary code from u-boot_mod/u-boot/cpu/mips/start_bootstrap.S.

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-3/+12
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

* Abolish cpu_read* and cpu_write* accessorsMasahiro Yamada2015-05-201-2/+2
| | | | | | | | | | | | | | Commit 2e6a88f2101d (add cpu native ordered io accessors) introduced these macros and then commit be57f20cdd7d (Fix big endian MMIO primitives) figured out they are equivalent to __raw_{read,write}*. They turned out unnecessary after all. Anyway, most source files use __raw_read* and __raw_write*. Let's replace a few remaining references and abolish them.

| | | | | | | | | | | | | | | | This board support code can be used for TP-LINK WR703 too. TP-LINK WR703 is very similar to TP-LINK MR3020, there are some non-essential differences: * WR703 is smaller and cheaper; * WR703 has only one led, but MR3020 has five leds; * MR3020 uses mini-USB connector, WR703 uses micro-USB connector.
