| | | | | | | | When later we change to variable length header, we won't know the file size when set_imx_hdr is called. So this is prep work. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

| | | | | | | | | | | | | | | | | | | | | | | | Add the software workaround for ARM erratum ID 468414. According to mx53/mx51 errata document: "ENGcm11133 - ARM: NEON load data can be incorrectly forwarded to a subsequent request Description: Under very specific set of conditions, data from a Neon load request can be incorrectly forwarded to a subsequent, unrelated memory request. The conditions are as follows: • Neon loads and stores must be in use • Neon L1 caching must be disabled • Trustzone must be configured and in use • The secure memory address space and the non-secure memory address space both use the same physical addresses, either as an alias or the same memory location or for separate memory locations The issue is reported by ARM, erratum ID 468414, Category 2" Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* mx53loco: Adapt the IPU clockFabio Estevam2012-10-17-1/+1
| | | | | | | Since PLL2 now has changed, it is necessary to adapt the CONFIG_IPUV3_CLK accordingly. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* mx5: lowlevel_init.S: Fix PLL settings for mx53Fabio Estevam2012-10-17-33/+67
| | | | | | | | | | | | | | | | | | Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz. Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz instead. Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI at 1080p because the IPU clock cannot reach the requested frequency. Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its maximum frequency. Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little bit to allow easier comparison with the original clock setup from FSL U-boot.

* mx5: lowlevel_init.S: Split init_clock macroFabio Estevam2012-10-17-30/+65
| | | | | | | | | | | init_clock is currently shared between mx51 and mx53 and it contains lots of ifdef's which makes it really hard to follow the code. Split the init_clock between mx51 and mx53 to allow easier readability. No functional changes are made. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* i.MX6: mx6qsabrelite: Add splash screen supportEric Nelson2012-10-16-1/+343
| | | | | | | | | | | | | | | | | | | | | Adds support for HDMI, two LVDS panels and one RGB panel to the SABRE-Lite board. Displays supported: HDMI - 1024 x 768 for maximum compatibility Hannstar-XGA - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1) wsvga-lvds - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600) wvga-rgb - 800 x 480 RGB (Boundary p/n Nit6X_800x480) Since the ipuv3_fb display driver currently supports only a single display, this code auto-detects panel by probing the HDMI Phy for Hot Plug Detect or the I2C touch controller of the LVDS and RGB displays in the priority listed above. Setting 'panel' environment variable to one of the names above will override auto-detection. Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>

* mx6qsabreauto: Pass the board revision to the kernelFabio Estevam2012-10-16-2/+52
| | | | | | | | | | | The kernel from Freescale expects that the bootloader passes the board revision. Read the board revision and pass it via get_board_rev(). Without passing the board revision the kernel does not operate properly as the initialization of peripherals are different in revA versus revB boards.

* mxc: Fix SDHC multi-instance clockBenoît Thébaudeau2012-10-16-2/+40
| | | | | | | | | | | | | | | | | | On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not suitable for the multi-instance use case (initialization made directly with fsl_esdhc_initialize()). This patch fixes this issue by adding a configuration field for the SDHC input clock frequency.

* mx35: Fix eSDHC clocksBenoît Thébaudeau2012-10-16-3/+15
| | | | | | | | | | | | | | Each eSDHC instance has a dedicated clock. gd->sdhc_clk must also be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).

| * bootstage: Add feature to stash/unstash bootstage infoSimon Glass2012-10-03-0/+188
| | | | | | | | | | | | | | | | | | | | | | | | It is useful to be able to write the bootstage information to memory for use by a later utility, or the Linux kernel. Provide a function to do this as well as a function to read bootstage information back and incorporate it into the current table. This also makes it possible for U-Boot to chain to another U-Boot and pass on its bootstage information. Signed-off-by: Simon Glass <sjg@chromium.org>
| * bootstage: Store boot timings in device treeSimon Glass2012-10-02-6/+120

| * bootstage: Add time accumulation featureSimon Glass2012-10-02-3/+60
| | | | | | | | | | | | | | | | | | | | | | Sometimes we want to add up the amount of time spent in a particular activity when it is happening in a number of discrete chunks. Add bootstage_start() to mark the start of an acitivity and bootstage_accum() to accumulate the time since the last start. Calling these function in pairs results in the accumulated time being collected. Signed-off-by: Simon Glass <sjg@chromium.org>

The base for the stylesheet is taken from: http://ds9a.nl/docbook/minimal-page.html I customized the CSS a bit further, for example to add curvy corners to example section and change the tint of gray.

* | kerneldoc: Implant DocBook from Linux kernelMarek Vasut2012-10-15-2/+3430
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull slightly modified version of Documentation/DocBook, the related perl script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and implant it into U-Boot. This will allow smooth generation of kerneldoc style documentation. It was necessary to modify the DocBook/Makefile to work with U-Boot build system. The changes were only minor though and involved replacing the kbuild specific parts. It was also necessary to replace use of variables like KERNEL_VERSION with U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so the generated result actually matches. Finally, it was necessary to adjust docproc.c, since the documentation in U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in case of the Linux kernel. Some parts of the DocBook Makefile are unused, but to allow easier sync with Linux kernel, these parts are still left in. The targets enabled now are "htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results of documentation build.
