SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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. Signed-off-by: Tom Rini

board: ti: am43: Fix DCDC3 voltage for epos-evm

2018-05-06T17:35:40Z

A common voltage of 1.35V was being programmed for all am43 board versions. EPOS-EVM Needs 1.20V for LPDDR2. Fixes: fc69d472621b5 (“board: ti: AM43XX: Add ddr voltage rail configuration”) Reported-by: James Doublesin Signed-off-by: Keerthy Reviewed-by: Tom Rini

spl: ti: Avoid serial calls when serial support is disabled

2018-04-28T22:32:23Z

If CONFIG_SPL_SERIAL_SUPPORT is not set, then the build will fail: board/ti/am335x/built-in.o: In function `spl_start_uboot': board/ti/am335x/board.c:247: undefined reference to `serial_tstc' board/ti/am335x/board.c:247: undefined reference to `serial_getc' Avoid the calls to the serial functions in that case.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48Z

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini

net: Move enetaddr env access code to env config instead of net config

2018-04-09T03:00:58Z

In order that we can use eth_env_* even when CONFIG_NET isn't set, move these functions to environment code from net code. This fixes failures such as: board/ti/am335x/built-in.o: In function `board_late_init': board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr' u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr' which caters for use cases such as: commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment variable") when Ethernet is required in Linux, but not U-Boot.

When compiling without CONFIG_CLOCK_SYNTHESIZER (which is implied by CONFIG_DRIVER_TI_CPSW for am335x_evm), exclude the network setup for AM335x-ICEv2 to avoid link time failures: board/ti/am335x/board.c:683: undefined reference to `setup_clock_synthesizer' Signed-off-by: Alex Kiernan

board: ti: am43xx: Define embedded_dtb_select for runtime DTB selection in U-boot

2018-04-07T00:45:44Z

AM437x QSPI boot is a single stage boot and hence needs runtime DTB selection to support AM437x-SK and AM437x-IDK with DM enabled. This is required to move am43xx_evm_qspiboot_defconfig to use DM/DT. Signed-off-by: Vignesh R Reviewed-by: Lokesh Vutla

ARM: AM43xx: Add support for RTC only + DDR in self-refresh mode

2018-04-06T21:04:33Z

Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers for wakeup from RTC-only mode with DDR in self-refresh. Parse these registers during SPL boot and jump to the kernel resume vector if the device is waking up from RTC-only modewith DDR in Self-refresh. The RTC scratch register layout used is: SCRATCH0 : bits00-31 : kernel resume address SCRATCH1 : bits00-15 : RTC magic value used to detect valid config SCRATCH1 : bits16-31 : board type information populated by bootloader During the normal boot path the SCRATCH1 : bits16-31 are updated with the eeprom read board type data. In the rtc_only boot path the rtc scratchpad register is read and the board type is determined and correspondingly ddr dpll parameters are set. This is done so as to avoid costly i2c read to eeprom. RTC-only +DRR in self-refresh mode support is currently only enabled for am43xx_evm_rtconly_config. This is not to be used with epos evm builds.

Add support for BeagleBoard.org PocketBeagle

2018-04-06T21:04:33Z

Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x 55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more. https://beagleboard.org/pocket This was tested using the am335x_evm_usbspl_defconfig. Note that MII pins are enabled despite not having Ethernet on this board. This avoids an issue where otherwise many timeout errors would be generated.

Convert all of CONFIG_CONS_INDEX to Kconfig

2018-03-16T14:28:52Z

This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.
