ARM: imx6sx-sdb: remove PHY reset GPIO from DT ...

The board file already has a more sophisticated PHY reset sequence,
so there is no need to do it in the driver.

nvmem: ocotp: Change TIMING calculation algorithm ...

Port of patch from linux-arm-kernel:
| From: Bryan O'Donoghue <pure.logic@nexus-software.ie>
|
| nvmem: imx-ocotp: Change TIMING calculation to u-boot algorithm
|
| The RELAX field of the OCOTP block is turning out as a zero on i.MX8MM.
| This messes up the subsequent re-load of the fuse shadow registers.
|
| After some discussion with people @ NXP its clear we have missed a trick
| here in Linux.
|
| The OCOTP fuse programming time has a physical minimum 'burn time' that is
| not related to the ipg_clk.
|
| We need to define the RELAX, STROBE_READ and STROBE_PROG fields in terms of
| desired timings to allow for the burn-in to safely complete. Right now only
| the RELAX field is calculated in terms of an absolute time and we are
| ending up with a value of zero.
|
| This patch inherits the u-boot timings for the OCOTP_TIMING calculation on
| the i.MX6 and i.MX8. Those timings are known to work and critically specify
| values such as STROBE_PROG as a minimum timing.

nvmem: ocotp: Ensure WAIT bits are preserved ...

Port of patch from linux-arm-kernel:
| From Bryan O'Donoghue <pure.logic@nexus-software.ie>
|
| nvmem: imx-ocotp: Ensure WAIT bits are preserved when setting timing
|
| The i.MX6 and i.MX8 both have a bit-field spanning bits 27:22 called the
| WAIT field.
|
| The WAIT field according to the documentation for both parts "specifies
| time interval between auto read and write access in one time program. It is
| given in number of ipg_clk periods."
|
| This patch ensures that the relevant field is read and written back to the
| timing register.

nvmem: ocotp: Elongate OCOTP_CTRL_ADDR field ...

Port of patch from linux-arm-kernel:
| From: Bryan O'Donoghue <pure.logic@nexus-software.ie>
|
| nvmem: imx-ocotp: Elongate OCOTP_CTRL ADDR field to eight bits
|
| i.MX6 defines OCOTP_CTRLn:ADDR as seven bit address-field with a one bit
| RSVD0 field, i.MX7 defines OCOTP_CTRLn:ADDR as a four bit address-field
| with a four bit RSVD0 field.
|
| i.MX8 defines the OCOTP_CTRLn:ADDR bit-field as a full range eight bits.
|
| i.MX6 and i.MX7 should return zero for their respective RSVD0 bits and
| ignore a write-back of zero where i.MX8 will make use of the full range.
|
| This patch expands the bit-field definition for all users to eight bits,
| which is safe due to RSVD0 being a no-op for the i.MX6 and i.MX7.

mvebu: make the compiler inline mvebu_remap_registers ...

Without that gcc 7.3.1 (from OSELAS.Toolchain-2018.02.0) makes
mvebu_remap_registers a standalone function which in its prolog saves
two registers to the stack. However this function is called early during
startup when there is no stack available yet and sp still points into
the nirvana which makes barebox crash.

serial_ns16550: readd support for mvebu armada 38x ...

The armada 38x device tree traditionally used "snps,dw-apb-uart" as
compatible for the internal UARTs. This was changed in Linux by commit
b7639b0b15dd ("serial: 8250_dw: Limit dw8250_tx_wait_empty quirk to
armada-38x devices") which was imported into barebox in e4067b75fb6c
("dts: update to v4.18-rc1") to "marvell,armada-38x-uart".

Teach the driver about the new compatible to make the console work
again.

ARM: Initial OP-TEE support ...

This adds initial support for OP-TEE, see https://www.op-tee.org/

barebox starts in secure mode as usual. When booting a kernel
the bootm code also loads the optee_os binary. Instead of jumping
into the kernel barebox jumps into the optee_os binary and puts
the kernel execution address into the lr register. OP-TEE then
jumps into the kernel in nonsecure mode.

The optee_os binary is passed with the -t option to bootm or
with global.bootm.tee.

Optionally OP-TEE can be compiled into barebox using the builtin firmware
feature. Enable the Kconfig option and place or link your tee binary as
optee.bin into the firmware directory.

The amount of SDRAM which is kept free for OP-TEE is configurable.

This patch was tested on a i.MX6 Nitrogen6x board.
