2015-11-19video: Drop unused console functionsSimon Glass
CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and CONFIG_CONSOLE_TIME are not used by any board. The implementation is not great and stands in the way of a refactor of i8042. Drop these for now. They can be re-introduced quite easily later, perhaps with driver-model real-time-clock (RTC) support. When reintroducing, it might be useful to make a few changes: - Blink time would be more useful than blink count - The confusing #ifdefs should be avoided - The time functions should support driver model - It would be best keyed off console_tstc() or some similar idle loop rather than a particular input driver (i8042 in this case) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2015-08-26video: cfb_console: Allow VGA device to work without i8042 keyboardBin Meng
So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device will try to initialize a keyboard device (for x86, it is i8042). But if i8042 controller initialization fails (eg: there is no keyboard connected to the PS/2 port), drv_video_init() just simply returns. This kills the opportunity of using a usb keyboard later with the vga console, as the vga initialization part is actually ok, only keyboard part fails. Change the code logic to allow this.

2015-08-14cfbconsole: Add support for stride != widthHans de Goede
cfbconsole currently assumes that the width and stride of the framebuffer are the same, in most places where stride matters it uses a VIDEO_LINE_LEN helper macro. This commit changes the few places not using VIDEO_LINE_LEN to also use VIDEO_LINE_LEN, and protects the default VIDEO_LINE_LEN with a #ifndef guard, allowing the boards config.h to override and, and thus support cases where stride != width.

2015-04-16x86: video: Allow keyboard presence to be controlled by device treeSimon Glass
At present a VGA console assumes a keyboard unless a CONFIG option is set. This difference can be dealt with by a device tree option, allowing boards that are otherwise the same to use the same configuration. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-01-23x86: video: Add support for CONFIG_CONSOLE_SCROLL_LINESSimon Glass
Some machines are very slow to scroll their displays. To cope with this, support the CONFIG_CONSOLE_SCROLL_LINES option. Setting this to 5 allows the display to operate at an acceptable speed by scrolling 5 lines at a time. This same option is available for LCDs so when these systems are unified this code can be unified also. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>

U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
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>
2014-07-23stdio: Remove redundant code around stdio_register() callsSimon Glass
There is no point in setting a structure's memory to NULL when it has already been zeroed with memset(). Also, there is no need to create a stub function for stdio to call - if the function is NULL it will not be called. This is a clean-up, with no change in functionality.

2014-03-10cfb_console: align fields in gzipped .bmp filesEric Nelson
.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. Refer to these files for more details: doc/README.displaying-bmps Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
