2018-09-25spl: Weed out CONFIG_SYS_TEXT_BASE usageMarek Vasut1-2/+1
The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location is available and can be corrupted by loading ie. uImage or fitImage headers there. Sometimes it could be beneficial to load the headers elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we still want to parse the image headers in some local onchip memory to ie. extract firmware from that image. Add the possibility to override the location where the headers get loaded by introducing new function, spl_get_load_buffer() which takes two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the data that are to be loaded there -- and returns a valid buffer address or hangs the system. The default behavior is the same as before, add the offset to CONFIG_SYS_TEXT_BASE and return that address. User can override the weak spl_get_load_buffer() function though.

2018-07-10spl: fat: Support full fitImage handlingMarek Vasut1-1/+12
Handle the case where the full fitImage support is enabled. In this case, the whole fitImage must be loaded up front as some parts of the fitImage code require memory-mapped access to the entire fitImage.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada1-1/+1
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass1-2/+2
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.
