* video: speedup writing strings to fb consoleSoeren Moch2014-10-30-0/+9
| | | | | | | | | | | With enabled framebuffer console the printenv command can take several seconds to complete. This patch temporarily disables cache flush when writing strings to fb console. Then there is no noticable delay anymore. Tested with imx6 hdmi framebuffer. Signed-off-by: Soeren Moch <smoch@web.de> Acked-by: Stefano Babic <sbabic@denx.de>

* video: ipu_disp: remove pixclk fixupJeroen Hofstee2014-10-16-25/+6
| | | | | | | | | | | | | | The ipu display insists on having a lower_margin smaller then 2. If this is not the case it will attempt to force it and adjust the pixclk accordingly. This multiplies pixclk in Hz with the width and height, since this is typically a * 10^7 * b * 10^2 * c * 10^2 this will overflow the uint_32 and make things even worse. Since this is a bootloader and the adjustment is neglectible, just force it to two and warn about it. Cc: Stefano Babic <sbabic@denx.de> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

| | | | | | | | | | | | | | | | | | | | | | On Exynos5420 and newer versions, the FIMD sysmmus are in "on state" by default. We have to disable them in order to make FIMD DMA work.

| * exynos_fb: Remove usage of static definesAjay Kumar2014-09-05-12/+6

Introducing the function exynos_lcd_early_init() would take care of this assignment on the fly by parsing FIMD DT properties, thereby allowing us to remove LCD_XRES and LCD_YRES from the main config file.

* video: ipu_disp: wait for DP SF end irq when disabling sync BG flowsLiu Ying2014-08-11-19/+19
| | | | | | | | | | | | Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end interrupt to come when disabling sync BG flows. In this way, we align the implement to the freescale internal IPUv3 driver. After applying this patch, an uboot hang up issue at the arch_preboot_os() stage, where we disable a relevant ipu display channel, is not observed any more on some MX6DL platforms.

* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

* cfb_console: align fields in gzipped .bmp filesEric Nelson2014-03-10-2/+6
| | | | | | | | | | | | | | | | | | | .bmp files contain 32-bit integers aligned at offsets of +2, +6, et cetera within the bmp_header structure (see include/bmp_layout.h). Support for gzip-compressed .bmp files is present in the cfb_console display subsystem by uncompressing them prior to use. This patch forces the in-memory header to be aligned properly for these compressed images by extracting them to a 2-byte offset in the memory returned by malloc. Since malloc will always return a 4-byte aligned value, this forces the .bmp header fields to be naturally aligned on 4-byte addresses.
