2020-09-18cmd: mem: fix range of bitflip testRalph Siemsen
The bitflip test uses two equal sized memory buffers. This is achieved by splitting the range of memory into two pieces. The address of the second buffer, as well as the length of each buffer, were not correctly calculated. This caused bitflip test to access beyond the end of range. This patch fixes the pointer arithmetic problem. A second problem arises because u-boot "mtest" command expects the ending address to be inclusive. When computing (end - start) this results in missing 1 byte of the requested length. The bitflip test expects a count rather than an "ending" address. Thus it fails to test the last word of the requested range. Fixed by using (end - start + 1). Added Kconfig option to optionally disable the bitflip test, since it does add significantly to the time taken for "mtest".

The commit e519f03a1846 ("cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping") removed CONFIG_SYS_MEMTEST_SCRATCH but commit 091401131085 ("command: Remove the cmd_tbl_t typedef") has added it back.

2020-08-07cmd: Update the memory-search commandSimon Glass
Add various fixes and improvements to this command that were missed in the original version. Unfortunately I forgot to send v2. - Fix Kconfig name - Use a separate variable for the remaining search length - Correct a minor bug - Move into a separate test suite - Add -q flag to the 'quiet' test to test operation when console is enabled - Enable the feature for sandbox Signed-off-by: Simon Glass <sjg@chromium.org>

It is useful to be able to find hex values and strings in a memory range. Add a command to support this. cmd: Fix 'md' and add a memory-search command At present 'md.q' is broken. This series provides a fix for this. It also implements a new memory-search command called 'ms'. It allows searching memory for hex and string data. END Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-08cmd: mem: Drop #ifdef for MEM_SUPPORT_64BIT_DATASimon Glass
This is defined only when __lp64__ is defined. That means that ulong is 64 bits long. Therefore we don't need to use a separate u64 type on those architectures.

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it.

2020-05-08cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mappingMichal Simek
There is no real need to exactly define space for saving patterns for alternate memory test. It is much easier to allocate space on the stack and use it instead of trying to find out space where pattern should be saved. For example if you want to test the whole DDR memory you can't save patter to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses were chosen but that means that OCM needs to be mapped and U-Boot has access permission there. It is easier to remove this limitation and simply save it on stack because it is very clear that memory test can't rewrite U-Boot and U-Boot has also full access to memory where runs from.

Both CMD_MX_CYCLIC and MX_CYCLIC are in use and defined in Kconfig, but only the non-CMD version currently does anything. This changes all usages to prefer the CMD_MX_CYCLIC option (since it's only affecting addition of the commands), and switches defconfigs using the non-CMD version to use the CMD version.

In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-02-12flash: complete CONFIG_SYS_NO_FLASH move with renamingMasahiro Yamada
We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is not completed. Finish this work by the tool. During this move, let's rename it to CONFIG_MTD_NOR_FLASH. Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH" than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will make the code more readable. Besides, negative meaning symbols do not fit in obj-$(CONFIG_...) style Makefiles. This commit was created as follows: [1] Edit "default n" to "default y" in the config entry in common/Kconfig. [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH" [3] Rename the instances in defconfigs by the following: find . -path './configs/*_defconfig' | xargs sed -i \ -e '/CONFIG_SYS_NO_FLASH=y/d' \ -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/' [4] Change the conditionals by the following: find . -name '*.[ch]' | xargs sed -i \ -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \ -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \ -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \ -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/' [5] Modify the following manually - Rename the rest of instances - Remove the description from README - Create the new Kconfig entry in drivers/mtd/Kconfig - Remove the old Kconfig entry from common/Kconfig - Remove the garbage comments from include/configs/*.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
