When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.Cc: Albert ARIBAUD

For aarch64, unsigned long is 64-bit data. Memory commands should be fixed

The directory name from an fdtdir directive in a PXE config file should
always be pre-pended to the DTB filename; it shouldn't matter whether
the DTB filename came from the $fdtfile environment variable, or whether
it was constructed dynamically from ${soc}-${board}.dtb. Fix the code to
always prepend the directory name.Reported-by: Dennis Gilmore

do_bootm_standanlone() calls ntohl(images->ep) which is wrong because
endianess conversion has already been done:do_bootm()
\-do_bootm_states()
+-bootm_find_os()
| \-images.ep = image_get_ep();
| \-uimage_to_cpu(hdr->ih_ep);
\-boot_selected_os()
\-do_bootm_standanlone()Without this conversion the code works correctly at least on AT91SAM9G45.
On big endian systems there should be no difference after applying this
patch because uimage_to_cpu(x) and ntohl(x) both expand to 'x'.Signed-off-by: Christian Eggers

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build objWe need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.Additionally, we need to fix compiler flags which are
locally added or removed.In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.Signed-off-by: Masahiro Yamada

This commit changes the working directory
where the build process occurs.Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-bootHere, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.And our old build system changes the current working directory
with "make -C " syntax when descending into the
sub-directories.On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
syntax for descending into sub-directories.
(We can write it like "make $(obj)=" with a shorthand.)
This means the current working directory is always the top
of the output directory.Signed-off-by: Masahiro Yamada

Add spl_sata to read a fat partition from a bootable SATA
drive.Signed-off-by: Dan Murphy
Reviewed-by: Roger Quadros -
Unlike other commands (for example, "fatwrite"), ext4write would
interpret the "sizebytes" as decimal number. This is not only
inconsistend and unexpected to most users, it also breaks usage
like this:tftp ${addr} ${name}
ext4write mmc 0:2 ${addr} ${filename} ${filesize}Change this to use the standard notation of base 16 input format.

This is much like a regular shell's -e operator, except that it takes
multiple arguments to specify the device type and device/partition ID
in addition to the usual filename:if test -e mmc 0:1 /boot/boot.scr; then echo yes; else echo no; fi

This emulates bash:
$ if test; then echo yes; else echo no; fi
noCurrently, the code sets expr = -1 in this case, which gets mapped to
0 (true) at the end of do_test() by the logical -> shell exit code
conversion.Signed-off-by: Stephen Warren

Currently, ! can only be parsed as the first operator in an expression.
This prevents the following from working:$ if test ! ! 1 -eq 1; then echo yes; else echo no; fi
yes
$ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi
yesFix this by parsing ! like any other operator, and and handling it
similarly to -a and -o.Signed-off-by: Stephen Warren

This better mirrors the behaviour of bash, for example:
$ if test -z = -z; then echo yes; else echo no; fi
yesThis is parsed as a string comparison of "-z" and "-z", since the check
for the binary "=" operator occurs first. Without this change, the
command would be parsed as a -z test of "-", followed by a syntax error;
a trailing -z without and operand.This is a behavioural change, but I believe any commands affected were
previously invalid or bizarely formed.Signed-off-by: Stephen Warren

do_test() currently uses strcmp() twice to determine which operator is
present; once to determine how many arguments the operator needs, then
a second time to actually decode the operator and implement it.Rewrite the code so that a table lookup is used to translate the operator
string to an integer, and use a more efficient switch statement to decode
and execute the operator.This approach also acts as enablement for the following patches.
This patch should introduce no behavioural change.
