tools: mkenvimage: Fix possible segfault on stdin input
The size of 'filebuf' was not increased as more and more bytes are read
from stdin, but 'filebuf' was always reallocated to the same fix size.
This works as long as only less bytes than the initial buffer size come
in, for more input this will segfault. (It actually does, I tested
that.) So for each loop cycle the buffer size has to be increased by the
number of bytes we want to read.
On success read() returns the number of bytes read or zero for EOF. On
error -1 is returned and errno is set, so the right way to test if read
had failed is to test the return value instead of errno.
Enable uart overrun feature which allows to benefits of uart
FIFO usage.
Previously overrun management was disabled, this has to effect
to bypassed the uart FIFO usage even if FIFO was enabled.
In particular configuration, for example when video console is
enabled, copy/pasting a long command line in console results in
corruption. This is due to the fact that a lot of time is consumed
in flushing the cache during frame buffer update, so uart chars are
not read fast enough.
By using uart FIFO and managing overrun, long command line can by
copy/paste in console without being corrupted.

kbuild: use -fmacro-prefix-map to make __FILE__ a relative path
The __FILE__ macro is used everywhere in U-Boot to locate the file
printing the log message, such as WARN_ON(), etc. If U-Boot is
built out of tree, this can be a long absolute path.
This is because Kbuild runs in the objtree instead of the srctree,
then __FILE__ is expanded to a file path prefixed with $(srctree)/.
A brand-new option from GCC, -fmacro-prefix-map, solves this problem.
If your compiler supports it, __FILE__ is the relative path from the
srctree regardless of O= option. This provides more readable log,
more reproducible builds, and smaller image size.

warp7: Add support for automated secure boot.scr verification
This patch adds support for verifying a signed boot.scr. With this in place
it's possible for run-time Linux to update boot.scr to set different
variables such as switching between different boot partitions, pointing to
different kernels etc and for u-boot to verify these changes via the HAB
prior to executing the commands contained in boot.scr.
setexpr allows us to do arithmetic for env variables - something that is
both useful and required when doing HAB authentication without hard-coding
HAB load addresses.
This patch enables CMD_SETEXPR for the WaRP7 defconfig.
warp7: hab: Set environment variable indicating IVT offset
This patch introduces the environment variable ivt_offset. When we define a
load address for Linux or DTB or any file the IVT associated with that file
is prepended. We extract the actual load addresses from u-boot.cfg and feed
these values into the code-signing process - hence we want u-boot to have
the real load addresses exported in uboot.cfg.
ivt_offset represents the addition or subtraction from the load address
that must happen to find an IVT header.
Doing secure boot on the WaRP7 using a common image format and the same
variable to represent the base address for each call means we can reduce
down the command to a single environment command.
This patch adds warp7_auth_or_fail as a wrapper around
"hab_auth_img_or_fail ${hab_ivt_addr} ${filesize} 0".
warp7: Define the name of a signed boot-script file
We need to know the name of a signed boot-script, its better to have a
separate variable for this then to simply append some fixed string to an
existing image name.
Assigning the UUID discovery path to a tweakable environment variable means
that later steps in the boot process - particularly a boot script can
change the target root partition of a particular Linux boot.
Retargeting the rootfs is an important feature when doing ping/pong
upgrades allowing a boot script to select ping or pong as necessary without
reprogramming the bootloader.
Adding CONFIG_WARP7_ROOT_PART allows a defconfig to specify which partition
is use as the root partition on WaRP7, this is a desirable change in order
to support a different partitioning schemes. The default is the current
partition #2.
In order to sign images with the IMX code-signing-tool (CST) we need to

printout of the relevant address ranges.
In order to correctly produce an image with a IVT/DCD header we need to
define a CSF in imximage.cfg. We just use the mx7 default here.
All we have to do with this option switched on is "make u-boot.imx" and we
then will get
- u-boot.imx
- u-boot.imx.log
The log file is really important because it gives the addresses for the HAB
that we will require to sign the u-boot image using the CST. Since the
addresses can change this logfile is a critical output.
This patch adds BOOTROM_IVT_HDR_OFFSET at 0xC00. The BootROM expects to
find the IVT header at a particular offset in an i.MX image.
Defining the expected offset of the IVT header in the first-stage BootROM
image format is of use of later stage authentication routines where those
routines continue to follow the first-stage authentication layout.
This patch defines the first stage offset which later patch make use of.

you are making a u-boot recovery image which the BootROM will accept via
the USB upload utility.
This disparity results in a fruity output like this with HAB Blocks
prefixed but DCD Blocks not prefixed - which is pretty inconsistent.
This patch fixes the difference assuming the original commit was a

sunxi: improve throughput in the sunxi_mmc driver
Throughput tests have shown the sunxi_mmc driver to take over 10s to
read 10MB from a fast eMMC device due to excessive delays in polling
loops.
This commit restructures the main polling loops to use get_timer(...)
to determine whether a (millisecond) timeout has expired. We choose
not to use the wait_bit function, as we don't need interruptability
with ctrl-c and have at least one case where two bits (one for an
error condition and another one for completion) need to be read and
using wait_bit would have not added to the clarity.
The observed speedup in testing on a A31 is greater than 10x (e.g. a
10MB write decreases from 9.302s to 0.884s).
