2017-10-16cmd/pxe.c: Rework bootargs construction to clarify string checksTom Rini
As the code currently stands, we first check that the length of the given command line, along with ip_str/mac_str along with an additional 1 for the NULL termination will fit within the buffer we have, and if not, we return an error. The way this code was originally written however left Coverity "unhappy" due to using strcat rather than strncat. Switching this to strncat however causes clang to be unhappy that we aren't enforcing the "1" portion within strncat. Rather than further re-work the code to include a "- 1" in this case as well, make the strcat code only be done within the else side of the length test. This keeps both clang and Coverity happy.

2017-10-06cmd/pxe.c: Rework initrd and bootargs handling slightlyTom Rini
For the initrd portion of handling our bootm arguments we do not have a sufficiently long enough buffer for some improbable 64bit cases. Expand this buffer to allow for a 64bit address and almost 256MB initrd to be used. Make use of strncpy/strncat when constructing the values here since we know what the worst case valid values are, length wise. Similarly for bootargs themselves, we need to make use of strlen/sizeof and strncpy/strncat to ensure that we don't overflow bootargs itself.

Rename this function for consistency with env_get(). Signed-off-by: Simon Glass <sjg@chromium.org>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
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.

2016-09-07pxe: Fix pxe boot with FIT imageYork Sun
When FIT image is used, a single image provides kernel, device tree and optionally ramdisk. Argc and argv need to be adjusted to support this. Test cases: 1. Booting with legacy images 2. Booting with legacy images without initrd 3. Booting with FIT image Test commands: 1. pxe get && pxe boot 2. sysboot Signed-off-by: York Sun <york.sun@nxp.com> Signed-off-by: Wenbin Song <wenbin.song@nxp.com>

2016-01-25Remove the cmd_ prefix from command filesSimon Glass
Now that they are in their own directory, we can remove this prefix. This makes it easier to find a file since the prefix does not get in the way.
