83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

97c16dc8bf imx: mx6ull: update the REFTOP_VBGADJ setting
According to design team, we need to set REFTOP_VBGADJ
in PMU MISC0 according to the REFTOP_TRIM[2:0] fuse. the
actually table is as below:

  '000" - set REFTOP_VBGADJ[2:0] to 3'b000
  '001" - set REFTOP_VBGADJ[2:0] to 3'b001
  '010" - set REFTOP_VBGADJ[2:0] to 3'b010
  '011" - set REFTOP_VBGADJ[2:0] to 3'b011
  '100" - set REFTOP_VBGADJ[2:0] to 3'b100
  '101" - set REFTOP_VBGADJ[2:0] to 3'b101
  '110" - set REFTOP_VBGADJ[2:0] to 3'b110
  '111" - set REFTOP_VBGADJ[2:0] to 3'b111

5b66482d44 imx: imx6ull: adjust the ldo 1.2v bandgap voltage
Per to design team, on i.MX6UL, the LDO 1.2V bandgap voltage
is 30mV higher, so we need to adjust the REFTOP_VBGADJ(anatop
MISC0 bit[6:4]) setting to 2b'110.

Check "Figure 19-5. BUS clock generation" of i.MX 6SoloX Applications
Processor Reference Manual and "Figure 18-5. BUS clock generation" of
i.MX 6UltraLite Applications Processor Reference Manual. If mmdc clk
sources from pll4_main_clk(pll_audio), the calculation is wrong.

6d97dc10a8 imx: clock support enet2 anatop clock support
To i.MX6SX/UL, two ethernet interfaces are supported.
Add ENET2 clock support:
1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed.
   To value 1, only i.MX6SX/UL can pass the check.
2. Modify board code who use this api to follow new api prototype.

43cb127b75 imx:mx6ul add clock support
1. Add enet, uart, i2c, ipg clock support for i.MX6UL.
2. Correct get_periph_clk, it should account for
   MXC_CCM_CBCDR_PERIPH_CLK2_PODF_MASK.
3. Refactor get_mmdc_ch0_clk to make all i.MX6 share one function,
   but not use 'ifdef'.
4. Use CONFIG_FSL_QSPI for enable_qspi_clk, but not #ifdef CONFIG_MX6SX.
5. Use CONFIG_PCIE_IMX for pcie clock settings, use CONFIG_CMD_SATA for
   sata clock settings. In this way, we not need "#if defined(CONFIG_MX6Q)
   || defined....", only need one CONFIG_PCIE_IMX in header file.

19c6ec70c5 imx: mx6 add i2c4 clock support for i.MX6SX
Add I2C4 clock support for i.MX6SX. Since we use runtime check,
but not macro, we need to remove `#ifdef ..` in crm_regs.h, or
gcc will fail to compile the code succesfully.

Making the macros only for i.MX6SX open to other i.MX6x maybe not
a good choice, but we have runtime check.

492938a334 nitrogen6x: Setup CCM_CCOSR register
CKO1 drives sgtl5000 codec clock on nitrogen boards and wandboard.

Doing this setup in the bootloader will allow us to remove a lot of code in
arch/arm/mach-imx/mach-imx6q.c from the mainline kernel.

Also, according to Eric Nelson: "enabling the clock <in the bootloader> will
remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."
