CPU sets DMA buffer descriptors with data required for inetrnal DMA such as: * Ownership of BD * Buffer size * Pointer to data buffer in memory Then we need to make sure DMA engine of NAND controller gets proper data. For this we flush buffer rescriptor. Then we're ready for DMA transaction. Signed-off-by: NAlexey Brodkin <abrodkin@synopsys.com> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Tom Rini <trini@ti.com>

Since TIZEN group has been used 450 X 140 bmp logo for lunchbox, this patch tries to change the logo size from 500 X 150 to official size. By reducing image size, we also save about 35KB. To make row aligned 4 bytes, add 2 pixels to row. Therefore the real width of image size is 452.

U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

U-Boot uses the 'mkimage' tool to produce various image types, not only uImage image type. Rename the invocation name from UIMAGE to MKIMAGE. The following command was used to do the replacement: git grep 'quiet_cmd_mkimage.* = UIMAGE' | cut -d : -f 1 | \ xargs -i sed -i "s@\(quiet_cmd_mkimage\)\(.*\) = UIMAGE @\1\2 = MKIMAGE@" {} Signed-off-by: NMarek Vasut <marex@denx.de> Cc: Tom Rini <trini@ti.com> Cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

For some time we have been using the run_command() with properly crafted string. Such approach turned to be unreliable and error prone. Switch to "native" mmc subsystem API would allow better type checking and shall improve speed. Also, it seems that this API is changing less often than u-boot commands. The approach similar to env operations on the eMMC has been reused. Signed-off-by: NLukasz Majewski <l.majewski@samsung.com>

The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: NPantelis Antoniou <panto@antoniou-consulting.com>

on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.

When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer is preserved in the jump by using a temporary file. Add an option to tell the receiving U-Boot to remove this file when it is no longer needed. Similarly the old U-Boot image is left behind in this case. We cannot delete it immediately since gdb cannot then find its debug symbols. Delete it just before exiting. Together these changes ensure that temporary files are removed both for memory and U-Boot.

Unfortunately SDL requires getenv() to operate, since it wants to figure out the display type. U-Boot has its own getenv() and they conflict. As a work-around use #define to resolve the conflict. A better but more complex solution might be to rename some U-Boot symbols at link time. SDL audio is not functional at present, likely due to a related issue.

SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right thing, since if ec_command() returns a -ve number we will consider this be success. Adjust all comparisons to avoid this problem. This error was found with sandbox, which gives a segfault in this case. On ARM we may instead silently fail. We should also consider turning on -Wsign-compare to catch this sort of thing in future.
