lmb: handle more than one DRAM BANK

2019-02-02T13:19:17+00:00

This fixes the automatic lmb initialization and reservation for boards
with more than one DRAM bank.

This fixes the CVE-2018-18439 and -18440 fixes that only allowed to load
files into the firs DRAM bank from fs and via tftp.

lib: lmb: rename lmb_get_unreserved_size to lmb_get_free_size

2019-01-26T13:13:57+00:00

As a follow-up, change the name of the newly introduced function
'lmb_get_unreserved_size' to 'lmb_get_free_size', which is more
appropriate.

lmb: remove unused extern declaration

lmb.h includes an extern declaration of "struct lmb lmb;" which
is not used anywhere, so remove it.

fs: prevent overwriting reserved memory

2019-01-16T21:37:05+00:00

This fixes CVE-2018-18440 ("insufficient boundary checks in filesystem
image load") by using lmb to check the load size of a file against
reserved memory addresses.

lib: lmb: extend lmb for checks at load time

2019-01-16T21:37:04+00:00

This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.

lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.

lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.

Added test for these new functions.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

image: Add device tree setup to image library

2013-05-14T19:37:25+00:00

This seems to be a common function for several architectures, so create
a common function rather than duplicating the code in each arch.

Also make an attempt to avoid introducing #ifdefs in the new code, partly
by removing useless #ifdefs around function declarations in the image.h
header.
