2015-04-01MIPS: Let __dt_register_buses accept a single bus typeKevin Cernekee1-1/+4
Some machines only have one bus type to register (e.g. "simple-bus").

2014-04-30mips: convert fdt pointers to opaque pointersRob Herring1-1/+1
The architecture code does not need to access the internals of the FDT blob directly, so make the pointers to it void * and use char arrays for section variables. Signed-off-by: Rob Herring <robh@kernel.org> Cc: Ralf Baechle <ralf@linux-mips.org> Tested-by: Grant Likely <grant.likely@linaro.org>

2013-10-09of: remove early_init_dt_setup_initrd_archRob Herring1-10/+0
All arches do essentially the same thing now for early_init_dt_setup_initrd_arch, so it can now be removed.

2013-07-24of: Specify initrd location using 64-bitSantosh Shilimkar1-2/+1
On some PAE architectures, the entire range of physical memory could reside outside the 32-bit limit. These systems need the ability to specify the initrd location using 64-bit numbers. This patch globally modifies the early_init_dt_setup_initrd_arch() function to use 64-bit numbers instead of the current unsigned long. There has been quite a bit of debate about whether to use u64 or phys_addr_t. It was concluded to stick to u64 to be consistent with rest of the device tree code. As summarized by Geert, "The address to load the initrd is decided by the bootloader/user and set at that point later in time. The dtb should not be tied to the kernel you are booting" More details on the discussion can be found here: https://lkml.org/lkml/2013/6/20/690 https://lkml.org/lkml/2012/9/13/544 Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>

2013-05-08MIPS: move mips_{set,get}_machine_name() to a more generic placeJohn Crispin1-0/+33
Previously this functionality was only available to users of the mips_machine api. Moving the code to prom.c allows us to also add a OF wrapper. Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/5164/

2012-02-24irq_domain/mips: Allow irq_domain on MIPSGrant Likely1-14/+0
This patch makes IRQ_DOMAIN usable on MIPS. It uses an ugly workaround to preserve current behaviour so that MIPS has time to add irq_domain registration to the irq controller drivers.

2011-10-31mips: migrate core kernel file from module.h --> export.hPaul Gortmaker1-1/+1
These files are not modules, but were including module.h only for EXPORT_SYMBOL and/or THIS_MODULE. Now that we have the lightweight export.h, use it in these kinds of cases. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-05-11dt/flattree: explicitly pass command line pointer to early_init_dt_scan_chosenGrant Likely1-1/+2
This patch drops the reference to a global 'cmd_line' variable from early_init_dt_scan_chosen, and instead passes the pointer to the command line string via the *data argument. Each architecture does something slightly different with the initial command line, so it makes sense for the architecture to be able to specify the variable name.

2011-01-15dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()Grant Likely1-4/+2
