* Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada2016-09-23-1/+0
| | | | | | | | | | | | | | Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone. Deprecate <asm/errno.h>. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Alexey Brodkin <abrodkin@synopsys.com>
* MIPS: Hang if run on a secondary CPUPaul Burton2016-09-21-0/+7
| | | | | | | | | | | | | Some systems are configured such that multiple CPUs begin running from their reset vector following a system reset. If this occurs then U-Boot will be run on multiple CPUs simultaneously, which causes all sorts of issues as the multiple instances of U-Boot clobber each other. Prevent this from happening by simply hanging with an infinite loop if we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum as appropriate, is non-zero.

* MIPS: Join the coherent domain when a CM is presentPaul Burton2016-09-21-0/+5
| | | | | | | | | | | MIPS Linux expects the bootloader to leave the boot CPU a member of the coherent domain when running on a system with a CM, and we will need to do so if we wish to make use of IOCUs to have cache-coherent DMA in U-Boot (and on some systems there is no choice in that matter). When a CM is present, join the coherent domain after completing cache initialisation. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* MIPS: L2 cache supportPaul Burton2016-09-21-0/+46
| | | | | | | | | | | | | | | This patch adds support for initialising & maintaining L2 caches on MIPS systems. The L2 cache configuration may be advertised through either coprocessor 0 or the MIPS Coherence Manager depending upon the system, and support for both is included. If the L2 can be bypassed then we bypass it early in boot & initialise the L1 caches first, such that we can start making use of the L1 instruction cache as early as possible. Otherwise we initialise the L2 first such that the L1s have no opportunity to generate access to the uninitialised L2. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

* MIPS: Preserve Config implementation-defined bitsPaul Burton2016-09-21-0/+1
| | | | | | | | | | The coprocessor 0 Config register includes 9 implementation defined bits, which in some processors do things like enable write combining or other functionality. We ought not to wipe them to 0 during boot. Rather than doing so, preserve their value & only clear the bits standardised by the MIPS architecture. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* MIPS: Probe cache line sizes once during bootPaul Burton2016-09-21-0/+13
| | | | | | | | | | | Rather than probing the cache line sizes on every call of any cache maintenance function, probe them once during boot & store the values in the global data structure for later use. This will reduce the overhead of the cache maintenance functions, which isn't a big deal yet but becomes more important once L2 caches which may expose their properties via coprocessor 2 or the CM are supported.

* MIPS: Split I & D cache line size configPaul Burton2016-05-31-0/+7
| | | | | | | | | | | | 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: 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.

* MIPS: Support dynamic I/O port base addressPaul Burton2016-02-01-21/+30
| | | | | | | | | | | | The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE.

* MIPS: kconfig: add option for MIPS_L1_CACHE_SHIFTDaniel Schwierzeck2016-01-16-10/+4
| | | | | | | | | | | | | | | | Add Kconfig symbol for L1 cache shift like the kernel does. The value of CONFIG_SYS_CACHELINE_SIZE is not a reliable source for ARCH_DMA_MINALIGN anymore, because it is optional on MIPS. If CONFIG_SYS_CACHELINE_SIZE is not defined by a board, the cache sizes are automatically detected and ARCH_DMA_MINALIGN would be set to 128 Bytes. The default value for CONFIG_MIPS_L1_CACHE_SHIFT is 5 which corresponds to 32 Bytes. All current MIPS boards already used that value. While on it, fix the Malta board to use a value of 6 like the kernel port does. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* mips: Use unsigned int when reading c0 registersChris Packham2015-08-21-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit a18a477 (MIPS: use common code from lib/time.c) MIPS platforms started using common the common timer functions which are based around the fact that many platforms have a 32-bit free running counter register that can be used see commit 8dfafdd (Introduce common timer functions). Even MIPS64 has such a 32-bit register (some have an additional 64-bit free running counter, but that's something for another time). The problem is that in __read_32bit_c0_register() we read the value from this register into an _signed_ int and as it's returned up the call chain to timer_read_counter() it gets assigned to an unsigned long. On a 32-bit system there is no problem. On a 64-bit system odd things happen, sign extension seems to kick in and all of a sudden if the counter register happens to have the MSb (i.e. the sign bit) set the negative int gets sign extended into a very large unsigned long value. This in turn throws out things from get_ticks() up. Update __read_32bit_c0_register() and __read_32bit_c0_ctrl_register() to use "unsigned int res;" instead of "int res;". There seems to be little reason to treat these register values as signed. They are either counters (which by definition are unsigned) or are made up of various bit fields to be interpreted as per the CPU datasheet.

* malta: use unmapped flash base addressGabor Juhos2013-11-15-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The physical base address of the NOR flash is 0x1e000000 on the Malta boards. The hardware also maps the first 4MiB of the flash into the 0x1fc00000-0x1fffffff range. Currently, U-Boot uses the mapped address to access the flash, which does not work in recent qemu versions. Since commit a427338b222b43197c2776cbc996936df0302f51 (mips_malta: correct reading MIPS revision at 0x1fc00010) writing to the mapped address space causes a CPU exception. Due to the exception, U-Boot hangs during boot when it tries to detect the CFI flash chip. Use the correct physical address for the MALTA_FLASH_BASE constant to fix the problem. In order to avoid relocation problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE constants. The change makes it possible to start U-Boot on a Malta board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also works on older versions (tested with 1.1.1, 1.2.2, 1.4.2, 1.5.3).

* malta: support for coreFPGA6 boardsPaul Burton2013-11-09-6/+29
| | | | | | | | | | | | | | | | | | | | | This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* mips32: detect L1 cache sizes if they're not definedPaul Burton2013-11-09-0/+6
| | | | | | | | | | | | | | | | For boards such as the MIPS Malta with an FPGA core card it is desirable to be able to detect the L1 cache sizes at runtime, since they are not dependant upon the board but on the FPGA bitstream in use. This patch performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are not defined by the board configuration. In cases where the sizes are detected this patch also removes the restriction that the I-cache & D-cache line sizes must be the same, as this is not necessarily true. If the cache sizes are defined by a configuration then they will be hardcoded as before, so this patch will not add overhead to such boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
