There are two enable methods supported by ARM64 Linux; psci and
spin-table. The latter is simpler and helpful for quick SoC bring
up. My main motivation for this patch is to improve the spin-table
support, which allows us to boot an ARMv8 system without the ARM
Trusted Firmware.
Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S
and the spin-table is supported in a really ad-hoc way, and I see
some problems:
- We must hard-code CPU_RELEASE_ADDR so that it matches the
"cpu-release-addr" property in the DT that comes from the
kernel tree.
- The Documentation/arm64/booting.txt in Linux requires that
the release address must be zero-initialized, but it is not
cared by the common code in U-Boot. We must do it in a board
function.
- There is no systematic way to protect the spin-table code from
the kernel. We are supposed to do it in a board specific manner,
but it is difficult to predict where the spin-table code will be
located after the relocation. So, it also makes difficult to
hard-code /memreserve/ in the DT of the kernel.
So, here is a patch to solve those problems; the DT is run-time
modified to reserve the spin-table code (+ cpu-release-addr).
Also, the "cpu-release-addr" property is set to an appropriate
address after the relocation, which means we no longer need the
hard-coded CPU_RELEASE_ADDR.

Upon further review this breaks most other platforms as we need to check
what core we're running on before touching it at all.

Add support for Advantech SOM-DB5800 with the SOM-6867 installed.
This is very similar to conga-qeval20-qa3-e3845 in that there is a
reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867)
installed.
Currently supported:
- 2x UART (From ITE EC on SOM-6867) routed to COM3/4 connectors on
SOM-DB5800.
- 4x USB 2.0 (EHCI)
- Video
- SATA
- Ethernet
- PCIe
- Realtek ALC892 HD Audio
Pad configuration for HDA_RSTB, HDA_SYNC, HDA_CLK, HDA_SDO
HDA_SDI0 is set in DT to enable HD Audio codec.
Pin defaults for codec pin complexs are not changed.
Not supported:
- Winbond Super I/O (Must be disabled with jumpers on SOM-DB8500)
- USB 3.0 (XHCI)
- TPM

This patch adds support to enable and use the internal BayTrail UART
instead of the one integrated in the Super IO Winbond chip. For this,
a 2nd defconfig file is added.
This is useful for tests done for the congatec SoM used on baseboards
without such a Super IO chip.

There are quite a number of BayTrail boards that uses an external
SuperIO chipset to provide the legacy UART. For such cases, it's
better to have a Kconfig option to enable the internal UART.
So far BayleyBay and MinnowMax boards are using internal UART as
the U-Boot console, enable this on these two boards.

Define a platform data structure for the MPC85XX GPIO driver to allow
use of the driver without device tree. Users should define the GPIO
blocks for their platform like this:
struct mpc85xx_gpio_plat gpio_blocks[] = {
{
.addr = 0x130000,
.ngpios = 32,
},
{
.addr = 0x131000,
.ngpios = 32,
},
};
U_BOOT_DEVICES(my_platform_gpios) = {
{ "gpio_mpc85xx", &gpio_blocks[0] },
{ "gpio_mpc85xx", &gpio_blocks[1] },
};
This is intended to build upon the recent submission of the base
MPC85XX driver from Mario Six. We need to use that new driver
without dts support and this patch gives us that flexibility.
This has been tested on a Freescale T2080 CPU, although only the first
GPIO block.
