global: Drop common.h inclusion

2023-12-21T13:54:37Z

In order to make it easier to move on to dropping common.h from code directly, remove common.h inclusion from the rest of the header file which had been including it. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

arm: Partial cleanup and audit usage of

2023-12-21T13:54:37Z

We need to include directly when a file needs to have something such as CFG_SYS_SDRAM_SIZE referenced as this file is not automatically globally included and is most commonly indirectly included via common.h. Remove most cases of arm including config.h directly, but add it where needed. This includes a few board-specific fixes. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

ddr: imx: Add 3600 MTps rate support

2023-12-14T18:29:08Z

Add PLL settings for DDR 3600 MTps . This is very similar to 3200 MTps PLL setting, except the divider is not 9 but 8 . Signed-off-by: Marek Vasut Reviewed-by: Fabio Estevam

ddr: imx: Handle 3734 in addition to 3733 and 3732 MTps rates

2023-12-14T18:29:08Z

The new MX8M DDR tool 3.31 now generates a programming file which uses data rate 3734 instead of 3733 or 3732 . Handle another rounding option . Signed-off-by: Marek Vasut Reviewed-by: Fabio Estevam

ddr: imx: Save the FW loading if it hasn't changed

2023-12-13T11:44:59Z

Function ddr_load_train_firmware() is called 4 times in a loop by ddr_cfg_phy(). The first 3 calls are all '1D' type and just loading the same FWs. Let's add a type check and save 2 of them. This helps to reduce DDRPHY training time from 269 ms down to 212 ms, and thus speed up boot time ~ 50 ms. Signed-off-by: Shawn Guo Reviewed-by: Fabio Estevam

treewide: unify the linker symbol reference format

2023-08-09T13:21:42Z

Now all linker symbols are declared as type char[]. Though we can reference the address via both the array name 'var' and its address '&var'. It's better to unify them to avoid confusing developers. This patch converts all '&var' linker symbol refrences to the most commonly used format 'var'. Signed-off-by: Shiji Yang Reviewed-by: Tom Rini
