* malta: IDE supportPaul Burton2015-01-29-0/+5
| | | | | | | | | This patch adds IDE support to the MIPS Malta board. The IDE controller is enabled after probing the PCI bus and otherwise just makes use of U-boot generic IDE support. Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: avoid .set ISA for cache operationsPaul Burton2015-01-29-0/+13
| | | | | | | | | | | | As a step towards unifying the cache maintenance code for mips32 & mips64 CPUs, stop using ".set <ISA>" directives in the more developed mips32 version of the code. Instead, when present make use of the GCC builtin for emitting a cache instruction. When not present, simply don't bother with the .set directives since U-boot always builds with -march=mips32 or higher anyway.

* MIPS: add support for pre-relocation mallocDaniel Schwierzeck2015-01-21-2/+0
| | | | | | | | | | | Implement MIPS specific setup of the gd_t structure to support pre-relocation malloc. If CONFIG_SYS_MALLOC_F_LEN is specified, a memory area will be reserved after the initial stack area and the gd->malloc_base pointer will be initialized. After this patch the new driver model can be used on MIPS. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* common/board_f: Initialized global data for generic boardYork Sun2014-05-12-0/+2
| | | | | | | | | | | | | Some platforms (tested on mpc85xx, mpc86xx) use global data before calling function baord_inti_f(). The data should not be cleared later. Any arch which uses global data in generic board board_init_f() should define CONFIG_SYS_GENERIC_GLOBAL_DATA.

* malta: enable PIIX4 SERIRQPaul Burton2013-11-26-0/+7
| | | | | | | | | | | | | Whilst U-boot does not require this itself, Linux currently relies upon it having been muxed and enabled by the bootloader. Thus in order to preserve compatibility with current kernels before a fix is merged in Linux we will enable the SERIRQ interrupt and mux it to its pin. Without doing this current kernels will never receive serial port interrupts and the end result is typically that userland appears to hang. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* 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: setup PIIX4 interrupt routePaul Burton2013-11-09-0/+5
| | | | | | | | | | | | Without setting up the PIRQ[A:D] interrupt routes, PCI interrupts will be left disabled. Linux does not set up this routing but relies upon it having been set up by the bootloader, reading back the IRQ lines which the PIRQ[A:D] signals have been routed to. This patch routes PIRQA & PIRQB to IRQ 10, and PIRQC & PIRQD to IRQ 11. This matches the setup used by YAMON. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

* 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>

* MIPS: fix __raw_* IO accessorsGabor Juhos2013-06-08-13/+13
| | | | | | | | | | | | | | The purpose of the __raw* IO accessors is to provide IO access in native-endian order.

* Introduce generic link section.h symbol filesSimon Glass2013-03-15-0/+27
| | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jz4740 is a multimedia application processor targeting for mobile devices like e-Dictionary, eBook, portable media player (PMP) and GPS navigator. Jz4740 is powered by Ingenic 360 MHz XBurst CPU core (JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture provides high integration, high performance and low power consumption. JzRISC incorporated in Jz4740 is the advanced and power-efficient 32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K D-Cache, and can operate at speeds up to 400 MHz. On-chip modules such as LCD controller, embedded audio codec, multi- channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich suite of peripherals for multimedia application. NAND controller (SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are also available. For more info about Ingenic XBurst Jz4740: http://en.ingenic.cn/eng/ http://www.linux-mips.org/wiki/Ingenic This patch introduces XBurst CPU support in U-Boot. It's compatible with MIPS32, but requires a bit different cache maintenance, timer routines, and boot mechanism using USB boot tool, so XBurst support can go into a separate new home, cpu/xburst/.
