a13f870ad4 rockchip: rk3399: default enable SPL LIBCOMMON and LIBGENERIC
We needs SPL LIBCOMMON and LIBGENERIC for all boards,
so we can enable them by default and no need to define
in each board.

70a64a070e arm: qemu: fix failure in flash initialization if booting from TF-A
If U-Boot is loaded and started from TF-A (you need to change
SYS_TEXT_BASE to 0x60000000), it will hang up at flash initialization.

If secure mode is off (default, or -machine virt,secure=off) at qemu,
it will provide dtb with two flash memory banks:
	flash@0 {
		bank-width = <0x4>;
		reg = <0x0 0x0 0x0 0x4000000 0x0 0x4000000 0x0 0x4000000>;
		compatible = "cfi-flash";
	};
If secure mode is on, on the other hand, qemu provides dtb with 1 bank:
	flash@0 {
		bank-width = <0x4>;
		reg = <0x0 0x4000000 0x0 0x4000000>;
		compatible = "cfi-flash";
	};

As a result, flash_init()/flash_get_size() will eventually fail.
With this patch applied, relevant CONFIG values are modified.

Currently, CONFIG_TFABOOT is located in armv8/fsl-layerscape Kconfig,
but it will be also useful for other targets if some additional
configuration are necessary.
So move it to arch/arm/Kconfig.

Please note that CONFIG_TFABOOT still depends on
CONFIG_ARCH_SUPPORT_TFABOOT and so the menu won't come up
if any target doesn't need its own customization for TF-A boot.
This will maintain the compatibility.

0c1456d571 ARM: correct detection of thumb mode
When a crash occurs in thumb mode the crash dump is incorrect. This is due
to the usage of a non-existing configuration variable CONFIG_ARM_THUMB in
the definition of macro thumb_mode(regs).

Use CONFIG_IS_ENABLED(SYS_THUMB_BUILD) to detect that the code has been
compiled for thumb mode. Remove ARM_THUMB from config_whitelist.txt.

With the patch crash dumps indicate thumb mode correctly.

board detection infrastructure introduced earlier to do the following:

1) Parse the AM654x EVM base board EEPROM and populate items like board
   name and MAC addresses into the TI common EEPROM data structure
   residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
   presence signals via an I2C-based GPIO expander. Then, if such a
   card is found, parse the data such as additional Ethernet MAC
   addresses from its on-board EEPROM and populate into U-Boot
   accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
   containing a list of daugherboard-specific DTB overlays based on
   daughercards found.

This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.

96905a39d3 arm: K3: am654: Map common EEPROM data into SRAM scratch space
The board detection scheme employed on various TI EVMs makes use of
SRAM scratch space to share data read from an on-board EEPROM between
the different bootloading stages. Map the associated definition that's
used to locate this data into the SRAM scratch space we use on AM654x.

ba7907c79c arm64: dts: k3-am654-base-board: Add I2C GPIO expander @ 0x38
The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the
wkup_i2c0 bus at address 0x38 that is used to detect the presence of
daughter cards.  Add a respective DTS description of this expander
to enable its use.

7e0363b285 arm: dts: k3-am654-base-board: Enable wkup_i2c0 across all boot stages
To enable the use of an EEPROM-based board detection scheme we need to
be able to access the I2C bus associated with the EEPROMs across all
3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go
ahead and add/update the wkup_i2c0 peripheral module DTS definitions
and its associated pinmux node accordingly.
