U-Boot has imported various source files from other projects,
mostly Linux.Something like
#ifdef __UBOOT__
[ modification for U-Boot ]
#else
[ original code ]
#endifis an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.Signed-off-by: Masahiro Yamada

If a 32-bit system has 2GB of RAM, and the base address of that RAM is
2GB, then start+size will overflow a 32-bit value (to a value of 0).__lmb_alloc_base is affected by this; it calculates the minimum of
(start+size of RAM) and max_addr. However, when start+size is 0, it
is always less than max_addr, which causes the value of max_addr not
to be taken into account when restricting the allocation's location.Fix this by calculating start+size separately, and if that calculation
underflows, using -1 (interpreted as the max unsigned value) as the
value instead, and then taking the min of that and max_addr. Now that
start+size doesn't overflow, it's typically large, and max_addr
dominates the min() call, and is taken into account.The user-visible symptom of this bug is that CONFIG_BOOTMAP_SZ is ignored
on Tegra124 systems with 2GB of RAM, which in turn causes the DT to be
relocated at the very end of RAM, which the ARM Linux kernel doesn't map
during early boot, and which causes boot failures. With this fix,
CONFIG_BOOTMAP_SZ correctly restricts the relocated DT to a much lower
address, and everything works.Signed-off-by: Stephen Warren

Remove the verified boot limitation that only allows a single
RSA public exponent of 65537 (F4). This change allows use with
existing PKI infrastructure and has been tested with HSM-based
PKI.Change the configuration OF tree format to store the RSA public
exponent as a 64 bit integer and implement backward compatibility
for verified boot configuration trees without this extra field.Parameterise vboot_test.sh to test different public exponents.

This simple function returns the node offset of a named alias.
Signed-off-by: Simon Glass
-
Aliases are used to provide U-Boot's numbering of devices, such as:
aliases {
spi0 = "/spi@12330000";
}spi@12330000 {
...
}This tells us that the SPI controller at 12330000 is considered to be the
first SPI controller (SPI 0). So we have a numbering for the SPI node.Add a function that returns the numbering for a node assume that it exists
in the list of aliases.Signed-off-by: Simon Glass

If we are to have driver model before relocation we need to support some
way of calling memory allocation routines.The standard malloc() is pretty complicated:
1. It uses some BSS memory for its state, and BSS is not available before
relocation2. It supports algorithms for reducing memory fragmentation and improving
performace of free(). Before relocation we could happily just not support
free().3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since
this has been loaded anyway this is not really a problem.The simplest way to support pre-relocation malloc() is to reserve an area
of memory and allocate it in increasing blocks as needed. This
implementation does this.To enable it, you need to define the size of the malloc() pool as described
in the README. It will be located above the pre-relocation stack on
supported architectures.Note that this implementation is only useful on machines which have some
memory available before dram_init() is called - this includes those that
do no DRAM init (like tegra) and those that do it in SPL (quite a few
boards). Enabling driver model preior to relocation for the rest of the
boards is left for a later exercise.Signed-off-by: Simon Glass

When this option is enabled, CRLF is treated like LF when importing environments
from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored.Drawback of enabling this option is that (maybe exported) variables which have
a trailing CR in their content will get imported without that CR. But this
drawback is very unlikely and the big advantage of letting Windows user create
a *working* uEnv.txt too is likely more welcome.Signed-off-by: Alexander Holler

As I initially suspected overflow in time handling, I took a detailed
look at lib/time.c. This adds comments about units being used, reduces
amount of type casting being done, and makes __udelay() always wait at
least one tick. (Current code could do no delaying at all for short
delays).Signed-off-by: Pavel Machek

it shows on boot:No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.cc: Simon Glass

It has been observed that fit_check_format() will fail when passed a
corrupt FIT image. This was tracked down to _fdt_string_eq():
return (strlen(p) == len) && (memcmp(p, s, len) == 0);In the case of a corrupt FIT image one can't depend on 'p' being NULL
terminated. I changed it to use strnlen() to fix the issue.Signed-off-by: Tom Rini

It seems the code tries to trick the compiler the argument

fool them so easily an now warn. Gcc and clang don't seem
to emit a warning when the argument is unused. If so it

Commit 2842c1c24269a05142802d25520e7cb9035e456c introduced lib/sha256 into
mkimage. Since then it will be compiled with HOSTCC which may produce errors
on some systems. Most BSD systems (like OS X for me) do not ship a
linux/string.h which will lead to take the U-Boot provided
include/linux/string.h in the end. This header howver is completely wrong
here. Just take the string.h if compiling with HOSTCC and linux/string.h when
not.Signed-off-by: Andreas Bießmann
