2013-02-12MIPS: xburst: fix broken access to global_dataDaniel Schwierzeck
Fix access to global_data which is broken since commits: commit 035cbe99cd2fd4adf9d7fd95aeebb5f814e37eb9 Author: Simon Glass <sjg@chromium.org> Date: Thu Dec 13 20:49:08 2012 +0000 mips: Move per_clk and dev_clk to arch_global_data Move these field into arch_global_data and tidy up. The other CONFIG_JZSOC fields are used by various architectures, so just remove the #ifdef bracketing for these.

2013-01-30MIPS: remove OUTPUT_FORMAT from linker scriptsGabor Juhos
The OUTPUT_FORMAT command in linker scripts was always misused due to some endianess and toolchain problems. Use GCC flags to ensure proper output format, and get rid of the OUTPUT_FORMAT commands in the board specific u-boot.lds files.

2013-01-30MIPS: xburst: simplify relocation offset calculationGabor Juhos
The current code uses four instructions and a temporary register to calculate the relocation offset and to adjust the gp register. The relocation offset can be calculated directly from the CONFIG_SYS_MONITOR_BASE constant and from the destination address. The resulting offset can be used to adjust the gp pointer. This approach makes the code a bit simpler because it needs two instructions only.

2013-01-30MIPS: simplify relocated _G_O_T_ address calculationGabor Juhos
The difference between the address of the original and the relocated _GLOBAL_OFFSET_TABLE_ is always the same as the relocation offset. The relocation offset is already computed and it is available in the 's1/t6' register. Use that to adjust the relocated _G_O_T_ address, instead of calculating the offset again from the _gp value.

2013-01-27MIPS: start.S: fix boundary check in relocate_codeGabor Juhos
The loop code copies more data with one than necessary due to the 'ble' instuction. Use the 'blt' instruction instead to fix that. Due to the lack of suitable hardware the Xburst specific code is compile tested only. However the change is quite obvious.

2012-10-17serial: Use default_serial_puts() in driversMarek Vasut
Replace the in-place ad-hoc implementation of serial_puts() within the drivers with default_serial_puts() call. This cuts down on the code duplication quite a bit. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>

2012-10-15serial: Remove CONFIG_SERIAL_MULTI from serial driversMarek Vasut
Remove the support for not-CONFIG_SERIAL_MULTI part from serial port drivers and some board files. Since CONFIG_SERIAL_MULTI is now enabled by default, that part is a dead code. Remove it.

2012-10-15serial: mips: Implement CONFIG_SERIAL_MULTI into JZ serial driverMarek Vasut
Implement support for CONFIG_SERIAL_MULTI into JZ serial driver. This driver was so far only usable directly, but this patch also adds support for the multi method. This allows using more than one serial driver alongside the JZ driver. Also, add a weak implementation of default_serial_console() returning this driver.

2012-08-17dm: mips: Fix lb60 timer codeMarek Vasut
The timer code contains more halfword writes which trigger gcc errors.

2011-10-10MIPS: Ingenic XBurst Jz4740 processor supportXiangfu Liu
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/.
