* ks2_evm: Add EEPROM based board detection helper functionsCooper Jr., Franklin2017-07-101-0/+20
| | | | | | | | | Add a function that can be used to determine if the board being ran on is a K2G Industrial Communication Engine EVM or K2G General Purpose EVM based on values programmed on the EEPROM. Signed-off-by: Franklin S Cooper Jr <fcooper@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* ARM: k2g: Program DDRPHY_DATX8 registers via mask and value variablesCooper Jr., Franklin2017-07-102-5/+41
| | | | | | | | | | Different K2G evms may need to program the various KS2_DDRPHY_DATX8_X_OFFSET registers in different ways. Therefore, use the mask and val registers for each KS2_DDRPHY_DATAX_X_OFFSET to properly program the register.

* ARM: k2g: Program DDR PHY MR2 register with the default valueCooper Jr., Franklin2017-07-102-3/+2
| | | | | | | | | | | K2G GP doesn't require the MR2 register to be programed since the default is good enough. However, newer K2G boards do need to change this register value. Therefore, instead of not writing this register if ran on a K2G board just program the value to be written to match the default/reset value.

* ks2_evm: Add EEPROM based board detectionCooper Jr., Franklin2017-07-102-21/+24
| | | | | | | | | | | | | Some K2G evms have their EEPROM programming while most do not. Therefore, add EEPROM board detection to be used as the default method and fall back to the alternative board detection when needed. Also reorder board configuration. Perform bare minimal configuration initially since board detection hasn't ran. Finish board configuration once the board has been identified.

| | | | | | | | | Now with support for U-boot runtime dtb selection each board needs to define board_fit_config_name_match so U-boot can determine what the correct dtb is within the FIT blob. Signed-off-by: Franklin S Cooper Jr <fcooper@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-bootCooper Jr., Franklin2017-07-102-0/+45
| | | | | | | | | | | | | | | | For K2G, runtime DTB selection utilizes the embedded_dtb_select function. Therefore, define the function which will perform a EEPROM read and then retries selecting the correct dtb now that it can detect which board its on. For other Keystone devices use an empty function since they will still use the embedded FIT functionality but their FIT will only contain a single dtb. Most production K2G boards do not have their EEPROM programmed. Therefore, perform a test to verify a K2G GP is currently being used and if it is then set the values normally set by a EEPROM read.

* board_f: Add new function to allow runtime DTB selectionCooper Jr., Franklin2017-07-103-0/+16
| | | | | | | | | | | | Runtime U-boot dtb selection is generally a two step process. First step is to simply use an initial generic dtb. The second step is to select the dtb and perhaps execute additional code ones U-boot knows what board it is running on. Embedded_dtb_select handles the second step by allowing board specific code to run and perform what ever necessary configuration that is needed.

| | | | | | | | | | | | When the EEPROM is first read its contents are stored in memory as a cache to avoid further I2C operations. To determine if the EEPROM was previously read the easiest way is to check the memory to see if the EEPROM's magic header value is set.

Those boards have been running U-Boot since 2010 and will have to be maintained until at least 2027. commit 5b8e76c35ec312a3f73126bd1a2d2c0965b98a9f ("powerpc, 8xx: remove support for 8xx") orphaned those boards by removing support for the mpc8xx CPU. This commit partially restores support for the 8xx, with the following limitations: - Restores support for MPC866 and MPC885 only - Does not restore IDE, PCMCIA, I2C, USB - Does not restore examples - Does not restore POST - Does not restore Ethernet on SCC - Does not restore console on SCC - Does not restore bedbug and kgdb support As the 866 and 885 do not support the following features, they are not restored either: - VIDEO / LCD - RTC clock The CPM uCODE patch is not restored either, because: - 866 and 885 already have support for I2C and SPI relocation without a uCODE patch - relocation of SMC, I2C or SPI is only needed for using SCCs for Ethernet or QMC The dynamic setup/calculation of clocks is removed, we expect the target being use with the clock and PLPRCR register defined in the configuration. All the clock settings for 8xx prior to 866 is removed as well as we now only support 866 and 885. This code is mature and addresses mature boards. Therefore all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif' is unneeded.

In order to keep traceability of the changes, they will be moved to their correct location and moved to Kconfig in a followup patch. This patch also declares CSSI as point of contact for the update of the 8xx platform, as those boards are the only ones still being maintained on the 8xx area.
