| * | ARM: ls102xa: Setting device's stream id for SMMUs.Xiubo Li2014-12-11-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LS1 has 4 SMMUs for address translation of the masters. All the SMMUs' stream IDs are 8-bit. The address translation depends on the stream ID of the incoming transaction. Each master has unique stream ID assigned to it and is configurable through SCFG registers. The stream ID for the masters is identical and share the same register field of STREAM ID registers. Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
| * | ARM: ls102xa: allow all the peripheral access permission as R/W.Xiubo Li2014-12-11-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Central Security Unit (CSU) allows secure world software to change the default access control policies of peripherals/bus slaves, determining which bus masters may access them. This allows peripherals to be separated into distinct security domains. Combined with SMMU configuration of the system masters privileges, these features provide protection against indirect unauthorized access to data. For now we configure all the peripheral access permissions as R/W. Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

So, run-time detection of the number of flash banks would be more user-friendly. Until this commit, UniPhier boards have achieved this by (ab)using board_flash_wp_on() because the boot failed if flash_size got zero. Fortunately, this problem was solved by commit 70879a92561a (flash: do not fail even if flash_size is zero). Now it is possible to throw away such a tricky workaround. This commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further refactoring. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

Eventually, this information can be used for tasks such as: - Allowing/preventing USB device mode; some models have a USB device on- board so only host mode makes sense. Others connect the SoC directly to the USB connector, so device-mode might make sense. - The on-board USB hub/Ethernet requires different GPIOs to enable it, although luckily the default appears to be fine so far. - The compute module contains an on-board eMMC device, so we could store the environment there. Other models use an SD card and so don't support saving the environment (unless we store it in a file on the FAT boot partition...) Set $fdtfile based on this information. At present, the mainline Linux kernel doesn't contain a separate DTB for most models, but I hope that will change soon.

It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. Consequently, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not support GPIO. In the first place, GPIO has nothing to do with OF_CONTROL. It is wrong that lib/fdtdec.c includes GPIO functions; it should be split into two files, FDT-common things and GPIO things. It is, however, a pretty big work to fix that correctly. This is a compromised commit to add a dummy <asm/arch/gpio.h> to support OF_CONTROL for UniPhier platform. This dummy header will be removed after FDT-GPIO stuff is fixed correctly. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* | | | sunxi: video: Add cfb console driver for sunxiLuc Verhaegen2014-11-25-0/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a fixed mode hdmi driver for the sunxi platform. The fixed mode is a relatively safe 1024x768, more complete EDID handling is currently not provided. Only HDMI is supported today. This code is enabled when HPD detects an attached monitor. Current config is such that 8MB is shaved off at the top of the RAM. This avoids several memory handling issues, most significant is the fact that on linux on ARM you are not allowed to remap known RAM as IO. A clued in display driver will be able to recycle this reserved RAM in future though. cfbconsole was chosen as it provides the most important functionality: a working u-boot console, allowing for the debugging of certain issues without the need for a UART.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | The data sheet just calls it DRAM_CLK_REG, and on sun6i we've both a dram_clk_cfg and dram_clk_gate, and the sun4i reg matches dram_clk_gate on sun6i, so name it the same on sun4i.
