d2b2ffe310 cmd_bootm.c: Add 'booti' for ARM64 Linux kernel Images
The default format for arm64 Linux kernels is the "Image" format,
described in Documentation/arm64/booting.txt.  This, along with an
optional gzip compression on top is all that is generated by default.
The Image format has a magic number within the header for verification,
a text_offset where the Image must be run from, an image_size that
includes the BSS and reserved fields.

This does not support automatic detection of a gzip compressed image.

857b9cb69f nios2: rebase nios2-generic board to 3c120 reference design
Though nios2-generic board meant to be a template, it is helpful

Design, it makes sense to rebase nios2-generic on this FPGA design.

fe20a81a68 Fix test failure caused by bad handling of ramdisk
Commit e3a5bbce broke the FIT image tests by not loading a ramdisk even if
a load address is provided in the FIT. The rationale was that a load address
of 0 should be considered to mean 'do not load'.

Add a new load operation which supports this feature, so that the ramdisk
will be loaded if a non-zero load address is provided.

9352697aa0 board/ti/dra7xx: add support for parallel NOR
This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM.
The Flash device is connected to GPMC controller on chip-select[0] and accessed
as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and
is CFI compatible.

As multiple devices are share GPMC pins on this board, so following board
settings are required to detect NOR device:
     SW5.1 (NAND_BOOTn) = OFF (logic-1)
     SW5.2 (NOR_BOOTn)  = ON  (logic-0) /* Active-low */
     SW5.3 (eMMC_BOOTn) = OFF (logic-1)
     SW5.4 (QSPI_BOOTn) = OFF (logic-1)

And also set appropriate SYSBOOT configurations:
     SW3.1 (SYSBOOT[ 8])= ON  (logic-1) /* selects SYS_CLK1 speed */
     SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
     SW3.3 (SYSBOOT[10])= ON  (logic-1) /* wait-pin monitoring = enabled */
     SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */
     SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */
     SW3.6 (SYSBOOT[13])= ON  (logic-1) /* device bus-width: 1(x16) */
     SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */
     SW3.8 (SYSBOOT[15])= ON  (logic-1) /* reserved */

As GPMC pins are shared by multiple devices, so in addition to this patch
following board settings are required for NAND device detection [1]:

  SW5.9 (GPMC_WPN)   = OFF (logic-1)
  SW5.1 (NAND_BOOTn) = ON  (logic-0) /* Active-low */
  SW5.2 (NOR_BOOTn)  = OFF (logic-1)
  SW5.3 (eMMC_BOOTn) = OFF (logic-1)
  SW5.4 (QSPI_BOOTn) = OFF (logic-1)

And also set appropriate SYSBOOT configurations
  SW2.1 (SYSBOOT[0]) = ON  (logic-1) /* selects NAND Boot */
  SW2.2 (SYSBOOT[1]) = OFF (logic-0) /* selects NAND Boot */
  SW2.3 (SYSBOOT[2]) = OFF (logic-0) /* selects NAND Boot */
  SW2.4 (SYSBOOT[3]) = OFF (logic-0) /* selects NAND Boot */
  SW2.5 (SYSBOOT[4]) = ON  (logic-1) /* selects NAND Boot */
  SW2.6 (SYSBOOT[5]) = ON  (logic-1) /* selects NAND Boot */
  SW2.7 (SYSBOOT[6]) = OFF (logic-0) /* reserved */
  SW2.8 (SYSBOOT[7]) = OFF (logic-0) /* reserved */

  SW3.1 (SYSBOOT[ 8])= ON  (logic-1) /* selects SYS_CLK1 speed */
  SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
  SW3.3 (SYSBOOT[10])= ON  (logic-1) /* wait-pin monitoring = enabled */
  SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Addr/Data Muxed */
  SW3.5 (SYSBOOT[12])= ON  (logic-1) /* device type: Addr/Data Muxed */

e53ad4b445 board/ti/am43xx: add support for parallel NAND
This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.

am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
  time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
  controlled by:
  (a) Statically using Jumper on connecter (J89) present on board.
  (a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
      by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
      SPI2_CS0 == 0: NAND (default)
      SPI2_CS0 == 1: eMMC

am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
  Thus only one of the two can be used at a time. Selection is controlled by:
  (a) Dynamically driving following GPIO pin from software
      GPMC_A0(GPIO) == 0 NAND is selected (default)

NAND device (MT29F4G08AB) on these boards has:
 - data-width=8bits
 - blocksize=256KB
 - pagesize=4KB
 - oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.

2475367670 km-powerpc: define CONFIG_PRAM to protect PHRAM and PNVRAM
When u-boot initializes the RAM (early in boot) it looks for the "pram"
env variable to know which is area it cannot use. If the "pram" env variable
is not found, the default CONFIG_PRAM value is used.

This value used to be 0 (no protection at all). This patch sets it to a
value that covers PHRAM and PNVRAM that must be protected in our case.

39446bcefa ARM: tegra: enable DFU too
Enable DFU protocol support (via the "dfu" command) on Tegra boards where
USB device/gadget mode is enabled.

Note that for DFU to operate correctly on Tegra, we still need some DFU
fixes/enhancements that are going through the DFU -> USB trees. However,
the code builds just fine without those changes, and applying this patch
now will allow both sets of patches to meet in the main U-Boot tree much
more quickly.

In order to run test/dfu/dfu_gadget_test.sh, you would need to add the
following to the board configuration:

CONFIG_EXT4_WRITE
CONFIG_CMD_EXT4_WRITE

However, I haven't enabled those here, since I believe the main use-case
for DFU on Tegra is raw flash writing, rather than filesystem access, so
we don't need the additional code-size hit. However, I could be persuaded
otherwise! We should probably add a separate test script for raw flash
access.

8cc96848f0 config: introduce a generic $bootcmd
This generic $bootcmd, and associated support macros, automatically
searches a defined set of storage devices (or network protocols) for an
extlinux configuration file or U-Boot boot script in various standardized
locations. Distros that install such a boot config file/script in those
standard locations will get easy-to-set-up booting on HW that enables
this generic $bootcmd.

Boards can define the set of devices from which boot is attempted, and
the order in which they are attempted. Users may later customize this
set/order by edting $boot_targets.

Users may interrupt the boot process and boot from a specific device
simply by executing e.g.:

$ run bootcmd_mmc1
or:
$ run bootcmd_pxe

This patch was originally written by Dennis Gilmore based on Tegra and
rpi_b boot scripts. I have made the following modifications since then:

* Boards must define the BOOT_TARGET_DEVICES macro in order to specify
  the set of devices (and order) from which to attempt boot. If needed,
  we can define a default directly in config_distro_bootcmd.h.

* Removed $env_import and related variables; nothing used them, and I
  think it's better for boards to pre-load an environment customization
  file using CONFIG_PREBOOT if they need.

* Renamed a bunch of variables to suit my whims:-)

CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts
to transfer large files. However, this means that individual write
operations will take a long time. Allow backends to specify a maximum
buffer size, so that each write operation is limited to a smaller data
block. This prevents the DFU protocol from timing out when e.g. writing
to SPI flash. I would guess that NAND might benefit from setting this
value too, but I can't test that.

0e285b503c dfu: fix some issues with reads/uploads
DFU read support appears to rely upon dfu->read_medium() updating the
passed-by-reference len parameter to indicate the remaining size
available for reading.

dfu_read_medium_mmc() never does this, and the implementation of
dfu_read_medium_nand() will only work if called just once; it hard-codes
the value to the total size of the NAND device irrespective of read
offset.

I believe that overloading dfu->read_medium() is confusing. As such,
this patch introduces a new function dfu->get_medium_size() which can
be used to explicitly find out the medium size, and nothing else.
dfu_read() is modified to use this function to set the initial value for
dfu->r_left, rather than attempting to use the side-effects of
dfu->read_medium() for this purpose.

Due to this change, dfu_read() must initially set dfu->b_left to 0, since
no data has been read.

dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left
when simply copying data from dfu->i_buf_start to the upload request
buffer. r_left represents the amount of data left to be read from HW.
That value is not affected by the memcpy(), but only by calls to
dfu->read_medium().

After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB
eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this
change, attempting to do that would result in DFU read returning no data
at all due to r_left never being set.

This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms

The PHY setup is derived from the Alwinner releases and Linux, but is mostly
undocumented.

The Allwinner AHCI controller also requires some magic (and, again,
undocumented) DMA initialisation when starting a port.  This is added under a
suitable ifdef.

This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on
contents of Linux DTS files, including SATA power pin config taken from the
DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

51148790f2 kconfig: switch to Kconfig
This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

  <target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
      <config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

77cd89e755 ARM: omap: fix GPMC address-map size for NAND and NOR devices
Fixes commit a0a37183bd
    ARM: omap: merge GPMC initialization code for all platform

1) NAND device are not directly memory-mapped to CPU address-space, they are
 indirectly accessed via following GPMC registers:
 - GPMC_NAND_COMMAND_x
 - GPMC_NAND_ADDRESS_x
 - GPMC_NAND_DATA_x
 Therefore from CPU's point of view, NAND address-map can be limited to just
 above register addresses. But GPMC chip-select address-map can be configured
 in granularity of 16MB only.
 So this patch uses GPMC_SIZE_16M for all NAND devices.

2) NOR device are directly memory-mapped to CPU address-space, so its
 address-map size depends on actual addressable region in NOR FLASH device.
 So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map
 size configuration.

3d31538625 k2hk: use common KS2_ prefix for all hardware definitions
Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and
add KS2_ prefix where it's needed. It requires to change names also
in places where they're used. Align lines and remove redundant
definitions in kardware-k2hk.h at the same time.

Using common KS2_ prefix helps resolve redundant redefinitions and
adds opportunity to use KS2_ definition across a project not thinking about
what SoC should be used. It's more convenient and we don't need to worry
about the SoC type in common files, hardware.h will think about that.
The hardware.h decides definitions of what SoC to use.

67ac6ffaee mtd: nand: davinci: add opportunity to write keystone U-boot image
The Keystone SoCs use the same NAND driver as Davinci.
This patch adds opportunity to write Keystone U-boot image to NAND
device using appropriate RBL ECC layout. This is needed only if RBL
boots U-boot from NAND device and that's supposed that raw u-boot
partition is used only for writing image.

The main problem is that default Davinci ECC layout is different from
Keystone RBL layout. To read U-boot image the RBL needs that image was
written using RBL ECC layout.

The BBT table is written using default Davinci layout and has to
be updated using one. The BBT can be updated only while erasing
chip or by forced bad block assigning, so erase function has to
use native ecc layout in order to be able to write BBT correctly.
So if we're writing to NAND U-boot address we use RBL layout for
others we use default ECC layout.

Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no
reasons to use ECC layout commands. It was added by mistake.

bb58503d80 dm: Add dm_scan_other() to locate board-specific devices
Some boards will have devices which are not in the device tree and do not
have platform data. They may be programnatically created, for example.
Add a hook which boards can use to bind those devices early in boot.

a327dee0f4 dm: Add child_pre_probe() and child_post_remove() methods
Some devices (particularly bus devices) must track their children, knowing
when a new child is added so that it can be set up for communication on the
bus.

Add a child_pre_probe() method to provide this feature, and a corresponding
child_post_remove() method.

e59f458de6 dm: Introduce per-child data for devices
Some device types can have child devices and want to store information
about them. For example a USB flash stick attached to a USB host
controller would likely use this space. The controller can hold
information about the USB state of each of its children.

The data is stored attached to the child device in the 'parent_priv'
member. It can be auto-allocated by dm when the child is probed. To
do this, add a per_child_auto_alloc_size value to the parent driver.

997c87bb0b dm: Add functions to access a device's children
Devices can have childen that can be addressed by a simple index, the
sequence number or a device tree offset. Add functions to access a child
in each of these ways.

The index is typically used as a fallback when the sequence number is not
available. For example we may use a serial UART with sequence number 0 as
the console, but if no UART has sequence number 0, then we can fall back
to just using the first UART (index 0).

The device tree offset function is useful for buses, where they want to
locate one of their children. The device tree can be scanned to find the
offset of each child, and that offset can then find the device.
