2013-08-13MIPS: bootm: drop obsolete Qemu specific bootm implementationDaniel Schwierzeck
The Qemu specific bootm implementation was intended for a special Qemu target in Linux kernel. But this target has been dropped in v2.6.25-rc1 by commit 302922e5f6901eb6f29c58539631f71b3d9746b8 Author: Ralf Baechle <ralf@linux-mips.org> Date: Tue Jan 29 10:15:02 2008 +0000 [MIPS] Qemu: Remove platform. The Qemu platform was originally implemented to have an easily supportable platform until Qemu reaches a state where it emulates a real world system. Since the latest release Qemu is capable of emulating the MIPSsim and Malta platforms, so this goal has been reached. The Qemu plaform is also rather underfeatured so less useful than a Malta emulation. Thus the special bootm implementation is obsolete by now and can be dropped. The Qemu support in U-Boot is going to be replaced by MIPS Malta board support. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

2013-08-13MIPS: bootm: add support for generic relocation of init ramdisksDaniel Schwierzeck

This patch moves all the font configuration values into video_font_data.h so they are all in the right place with the font.

2013-08-09dma: apbh: Add special circular mode for LCDMarek Vasut
Add special function that executes a specially crafted circular DMA descriptor. The function doesn't wait for the descriptor to finish the transfer, since the descritor never finishes. This is useful when operating a SmartLCD through the LCDIF interface, as the LCDIF does not give us any means to have continuous refresh of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register must be triggered manually. This can be worked around by starting an DMA transfer which continuously sets the RUN bit. This function allows starting exactly such transfer.

2013-08-08nds32: introduce DMA allocation APIken kuo
U-Boot does not compile for the adp-ag101 boards since commit a8f9cd1893bef05b92f63242228607b45821c4a7 (net: update FTGMAC100 for MMU/D-cache support) The driver assumes that the DMA allocation API are provided by all architectures. This is not the case for nds32 and it causes a build error. This patch adds DMA allocation API to avoid the errors.

2013-07-31blackfin: gpio: Use proper mask for comparing functionAxel Lin
The function return from P_FUNCT2MUX(per) takes 2 bits, however for BF537_FAMILY with offset != 1 the function is 1 bit. Also has small refactor for better readability. In portmux_setup(), it looks odd having "muxreg &= ~(3 << 1);" while in current code we do muxreg |= (function << offset);. Signed-off-by: Axel Lin <axel.lin@ingics.com>

This register is used by the Linux kernel to identify the actual board it is running on. However the register is not emulated properly by Qemu, so put a hardcoded value into the flash to make Linux work.

2013-07-24nds32: ag101/ag102: Fix setting lastdec and now valuesAxel Lin
The timer3 counter unit for lastdesc and now values are inconsistent in current code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is second. However, CONFIG_SYS_HZ is defined as 1000 in board config file. This means the accuracy of "lastdec" and "now" should be in millisecond, thus fix the equation to set lastdec and now variables accordingly. Signed-off-by: Axel Lin <axel.lin@ingics.com>
