Add tracing printings to Linux/Android boot commands, so that we can see
what's going on. Helps to trace possible bugs on early stages and
improves the output for user (which is especially useful, because we
have a bunch of boot commands executing one by one).Signed-off-by: Sam Protsenko

Extract commands for booting Linux from eMMC to separate command. It
seems more logical that way, and allows us to run the whole command set

Right now on OMAP5-based boards we have only one partition defined for
Linux boot, which is rootfs. That doesn't work with bootpart=1:2 (that
is defined in include/environment/ti/boot.h). To fix Linux boot we may
either:1. Change bootpart to be 1:1
2. Or add preceding partition, so that rootfs is actually 1:2Second choice seems more reasonable, as DFU is already using similar
partition table and can rely on bootpart to be 1:2.This patch adds "bootloader" partition. So now eMMC layout for Linux
boot looks like this:offset content size partition

Guard hole appears because U-Boot environment offset was calculated for
Android partition table, which has two additional partitions in place of
that hole ("environment" and "misc" partitions).This patch also changes rootfs offset from 2 MiB further to 2688 KiB,
so that there won't be any collisions with U-Boot environment when we
flash rootfs.Signed-off-by: Sam Protsenko

This patch adds support for authentication of both plain
text and encrypted binaries. A new SECDEV package is needed
to enable encryption of binaries by default for AM3x.The ROM authentication API detects encrypted images at
runtime and automatically decrypts the image if the
signature verification passes.Addition of encryption on AM3x results in a change in the
image format. On AM4x, AM5x and, on AM3x devices signing
clear test images, the signature is appended to the end of the
binary.On AM3x, when the SECDEV package is used to create signed
and encrypted images, the signature is added as a header
to the start of the binary. So the binary size calculation
has been updated to reflect this change.The signing tools and encrypted image format for AM3x
cannot be changed to behave like AM4x and AM5x to
maintain backward compatibility with older Sitara
M-Shield releases.Signed-off-by: Madan Srinivas

Corresponds to 375506d (File writing nit) from upstream
(https://github.com/ulfalizer/Kconfiglib).Adds proper 'imply' support and fixes a few minor issues, one of which
previously triggered the following weird warning:configs/taurus_defconfig: /tmp/tmpisI45S:6: warning: assignment to SPL_LDSCRIPT changes mode of containing choice from "arch/$(ARCH)/cpu/u-boot-spl.lds" to "y"
The change in 8639f69 (genconfig.py: Print defconfig next to warnings)
was reapplied.tools/moveconfig.py previously depended on a hack that merged 'select's
with 'imply's. It was modified to look at the union of
Symbol.get_selected_symbols() and Symbol.get_implied_symbols(), which
should give the same behavior.tools/genboardscfg.py was verified to produce identical board.cfg's
before and after the change.Signed-off-by: Ulf Magnusson

Checkpatch can use two dictionaries for finding typos:
* scripts/spelling.txt
* /usr/share/codespell/dictionary.txt
which comes with package codespell and is selected by parameter
--codespellIf the file scripts/spelling.txt is missing, a warning is shown.
Add the spelling.txt file from the Linux kernel 4.13 source.
We can later add our own typo corrections.

The MMC framework in U-Boot does not support a systematic API for
timing switch like mmc_set_timing() in Linux.U-Boot just provides a hook to change the clock frequency via
mmc_set_clock(). It is up to drivers if additional register
settings are needed.This driver needs to set a correct timing mode into a register when
it migrates to a different speed mode. Only increasing clock frequency
could result in setup/hold timing violation.The timing mode should be decided by checking MMC_TIMING_* like
drivers/mmc/host/sdhci-cadence.c in Linux, but "timing" is not
supported by U-Boot for now. Just use mmc->clock to decide the
timing mode.Signed-off-by: Masahiro Yamada

This patch adds SD/MMC support for STM32H7 SoCs.
Here is an extraction of SDMMC main features, embedded in
STM32H7 SoCs.
The SD/MMC block include the following:
_ Full compliance with MultiMediaCard System Specification
Version 4.51. Card support for three different databus modes:
1-bit (default), 4-bit and 8-bit.
_ Full compatibility with previous versions of MultiMediaCards
(backward compatibility).
_ Full compliance with SD memory card specifications version 4.1.
(SDR104 SDMMC_CK speed limited to maximum allowed IO speed,
SPI mode and UHS-II mode not supported).
_ Full compliance with SDIO card specification version 4.0.
Card support for two different databus modes: 1-bit (default)
and 4-bit. (SDR104 SDMMC_CK speed limited to maximum allowed IO
speed, SPI mode and UHS-II mode not supported).
_ Data transfer up to 208 Mbyte/s for the 8 bit mode.
(depending maximum allowed IO speed).
_ Data and command output enable signals to control external
bidirectional drivers.The current version of the SDMMC supports only one SD/SDIO/MMC card
at any one time and a stack of MMC Version 4.51 or previous.Signed-off-by: Christophe Kerello
