imx8m: ddrphy_utils: Remove unused file

2022-09-18T20:56:10Z

The ddrphy_utils.c is now deduplicated in drivers/ddr/imx/phy/ddrphy_utils.c , this drivers/ddr/imx/imx8m/ddrphy_utils.c is a remnant from when the deduplication was implemented and was not removed. Remove it as it is unused. Signed-off-by: Marek Vasut Cc: Fabio Estevam Cc: Peng Fan Cc: Stefano Babic Cc: Ye Li Cc: uboot-imx Reviewed-by: Fabio Estevam Reviewed-by: Peng Fan

ddr: fsl: Make bank_addr_bits reflect actual bits

2022-09-06T01:28:46Z

In both the Freescale DDR controller and the SPD spec, bank address bits are stored as the number of bank address bits minus 2. For example, if a chip had 8 banks (3 total bank address bits), the value of bank_addr_bits would be 1. This is rather surprising for users configuring their memory manually, since they can't set bank_addr_bits to the actual number of bank address bits. Rectify this. There is at least one example of this kind of mistake already, in board/freescale/t102xrdb/ddr.c. The documented MT40A512M8HX has two bank address bits, but bank_addr_bits was set to 2, implying 4 bank address bits. Such a value is reserved in BA_BITS_CS, but I suspect the controller simply ignores the top bit, making this kind of mistake harmless, if misleading.

ddr: fsl: Reduce the size of interactive options

2022-09-06T01:28:45Z

The interactive mode uses large several tables of options which can be configured. However, much of the contents of these tables are repetetive. For example, no struct is larger than half a kilobyte, so the offset only takes up 9 bits. Similarly, the size is only ever 4 or 8, and printhex is a boolean. Reduce the size of these fields. This reduces the size of the options tables by around 10 KiB. However, the largest contributor to the size of the options tables is the use of a pointer for the strings. A better approach would be to use a separate array of strings, and store an integer index in the options tables. However, this would require a large re-architecting of this file.

Convert CONFIG_SYS_FSL_DDR_MAIN_NUM_CTRLS et al to Kconfig

2022-08-12T20:10:49Z

This converts the following to Kconfig: CONFIG_SYS_FSL_DDR_MAIN_NUM_CTRLS CONFIG_SYS_FSL_OTHER_DDR_NUM_CTRLS And we remove the entries from the README for a number of already converted items. Signed-off-by: Tom Rini

ddr: imx8m: helper: load ddr firmware according to binman symbols

2022-07-26T09:29:02Z

By reading binman symbols, we no need hard coded IMEM_LEN/DMEM_LEN after we update the binman dtsi to drop 0x8000/0x4000 length for the firmware. And that could save binary size for many KBs.

ddr: imx: Add i.MX9 DDR controller driver

2022-07-26T09:29:01Z

Since i.MX9 uses same DDR PHY with i.MX8M, split the DDRPHY to a common directory under imx, then use dedicated ddr controller driver for each iMX9 and iMX8M. The DDRPHY registers are space compressed, so it needs conversion to access the DDRPHY address. Introduce a common PHY address remap function for both iMX8M and iMX9 for all PHY registers accessing.
