2f41ade79e linker: Modify linker scripts to be more generic
Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than
CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE.  This lets us re-use the
same script for both SPL and TPL.  Add logic to scripts/Makefile.spl to
pass in the right value when preprocessing the script.

Like AM33xx and AM43xx, DRA7xx and AM57xx devices may need to

to the device being a high security variant, which place the

a1702746df ARM: mach-omap2: omap3: Fix GPIO clocking in SPL
OMAP3_GPIO_x is needed to enable each GPIO bank on the OMAP3
boards. At one point, the #ifdef's were replaced with
if CONFIG_IS_ENABLED but this won't work for people who need
OMAP3_GPIO_x in SPL since the SPL prefix for this option isn't
used in Kconfig.  This patch moves the check to #if defined and
also makes Kconfig select the banks if CMD_GPIO is used which
makes the checks in the code less cumbersome.

platform  to have the best MMC performances.
To detect the board type/version an I2C EEPROM is read. This requires that
DM is initialized before the detection. As a consequence we must reset the
DM after the board detection is a new dtb would better match the platform.

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

for wakeup from RTC-only mode with DDR in self-refresh. Parse these
registers during SPL boot and jump to the kernel resume vector if the

The RTC scratch register layout used is:

SCRATCH0 : bits00-31 : kernel resume address
SCRATCH1 : bits00-15 : RTC magic value used to detect valid config
SCRATCH1 : bits16-31 : board type information populated by bootloader

During the normal boot path the SCRATCH1 : bits16-31 are updated with
the eeprom read board type data. In the rtc_only boot path the rtc
scratchpad register is read and the board type is determined and
correspondingly ddr dpll parameters are set. This is done so as to avoid
costly i2c read to eeprom.

RTC-only +DRR in self-refresh mode support is currently only enabled for
am43xx_evm_rtconly_config.
This is not to be used with epos evm builds.

it.  Next, consolidate all of these into the single entry in

package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include <libfdt.h>      -> #include <linux/libfdt.h>
  #include <libfdt_env.h>  -> #include <linux/libfdt_env.h>

5fbed8f2c6 ARM: Kconfig: Move TI_SECURE_DEVICE to a common area
TI_SECURE_DEVICE is used by both OMAP2+ and Keystone2 family devices,
and so when ARCH_OMAP2PLUS was used to gate off the OMAP2+ Kconfig
Keystone2 family devices lost this config option.

Move this option out of mach-omap2 Kconfig to a spot accessible by both
families. We picked arch/arm/Kconfig over the TI specific board/ti/
location as this option is not specific to our boards but rather our
architecture.

Plus at some point this option can be changed to just
SECURE_DEVICE, as having secure parts is not exclusive to TI and
so other vendors can interpret this option as needed by their device
configurations.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

0830d72bb9 arm: am33xx: security: adds auth support for encrypted images
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.

0459bc30b6 ARM: OMAP5: Enable support for AVS0 for OMAP5 production devices
OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.

Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.

scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.

On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1
4a0021c4: 03a003e9                               ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1
4a0021c8: 03400485                               ..@.

MM OPP_NOM:
=> md.l 0x04A0021A4 1
4a0021a4: 038003d4                               ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1
4a0021a8: 03600403                               ..`.

CORE OPP_NOM:
=> md.l 0x04A0021D8 1
4a0021d8: 000003cf                               ....
(0x3cf = 975mV) vs nom voltage of 1.040v

Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).

But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.

Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

Data based on OMAP5432 Technical reference Manual SWPU282AF (May
2012-Revised Aug 2016)

NOTE: All collaterals on OMAP5432 silicon itself seems to have been
removed from ti.com, though EVM details are still available:

b529993e02 spl: add hierarchical defaults for SPL_LDSCRIPT
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.

As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig.  Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.

409a81ddd4 am33xx: board: Refactor USB initialization into separate function
The declaration of otg*_plat and otg*_board_data is guarded by
CONFIG_USB_MUSB_*, but their use in arch_misc_init is not. The
ifdef flow goes something like:

if (CONFIG_USB_MUSB_* && other_conditions)
	declare usb_data
if (other_conditions)
	use usb_data

Thus when CONFIG_USB_MUSB_* is not declared, we try to use the
data structures, but these structures aren't defined.

To fix this, move the USB initialization code into the same #ifdef
which guards the declaration of the data structures. Since the DM_USB
vs legacy cases are completely different, use two versions of
arch_misc_init(), for readability.
