16a30b3474 doc: ti: add the K3 generation page
Texas Instrument's entire K3 generation of SoCs use much of the same
frameworks and boot flow, especially at the uboot level. Though there
are small differences introduced as each new K3 based SoC is developed
and as the K3 generation matures that will also need to be documented.

Rather than copying the same documentation, with the small differences
applicable to that specific SoC to a new page, introduce a new K3
page that can describe the general boot flow and design decisions for
the entire K3 generation of chips, leaving the specifics for that
particular SoC to a unique sub-page below this one.

0820e117c3 doc: ti: reorganize existing ti docs
Texas Instruments produces quite a lot of SoCs based upon a common
architecture 'generation'. (eg: OMAP, K3) TI's existing documentation
layout makes noticing this generation jump rather difficult.

To make navigation easier, split the existing documentation into
individual SoC families so we may begin grouping them according to their
generational (eg: OMAP, K3) families.

4e5909450e global: Move remaining CONFIG_SYS_NAND_* to CFG_SYS_NAND_*
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_NAND
namespace do not easily transition to Kconfig. In many cases they likely
should come from the device tree instead. Move these out of CONFIG

d5c4ec4aa3 board: axy17lte: get board usable - add bootcmd and docs
U-boot is intended to replace linux kernel in android boot image(ABL), and
it's FIT payload to replace initramfs file. The boot process is similar to
boot image with linux:
- android bootloader (ABL) unpacks android boot image
- ABL sets `linux,initrd-start property` in chosen node in unpacked FDT
- ABL sets x0 register to FDT address, and passes control to u-boot
- u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable
- u-boot reads `linux,initrd-start` property,
and stores it in `prevbl_initrd_start_addr`

In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env
variable, and boils down to `bootm $prevbl_initrd_start_addr`.
If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration

What done:
- Rearrange defconfig option order
- Add CONFIG_SAVE_PREV_BL_* options
- Doc updates:
  - remove wrong SBOOT memory corruption note, because
  memory is changed during u-boot bringup process,
  not by SBOOT
  - put payload on ramdisk place in abl boot image
  creation step

If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration

What done:
- strip unneeded config options
- add FIT image support
- add framebuffer node, u-boot logo and video console
- increase LMB_MAX_REGIONS, to store all linux dtb reserved memory regions
- add linux kernel image header

Uart driver causes hang, when u-boot is used in android boot image instead
of linux. Temporary disable console driver, until investigated and fixed.

93c3d32970 ls1046ardb: Add support for JTAG boot
This adds support for booting entirely from JTAG while using a
hard-coded RCW. With these steps, it is not necessary to program a
"good" RCW using CodeWarrior. The method here can be performed with any
JTAG adapter supported by OpenOCD, including the on-board CMSIS-DAP
(albeit very slowly).

These steps require LS1046A support in OpenOCD, which was added in [1].

This converts the readme for this board to rST. I have tried not to
change any semantics from the original (though I did convert MB to M).
