ti: am654: Drop duplicate dm.h inclusion

We only need to include this header once. Drop the duplicate. Signed-off-by: Simon Glass

ram: sifive: Avoid using hardcoded ram base and size

2020-07-24T06:56:29Z

At present the SiFive FU540 RAM driver uses hard-coded memory base address and size to initialize the DDR controller. This may not be true when this driver is used on another board based on FU540. Update the driver to read the memory information from DT and use that during the initialization. Signed-off-by: Bin Meng Reviewed-by: Leo Liang Reviewed-by: Pragnesh Patel

rockchip: ram: fix debug funcfion define when RAM_ROCKCHIP_DEBUG not set

2020-07-22T12:22:33Z

The empty function define should not be in the header file, or else the build will error with function multi definition after CONFIG_RAM_ROCKCHIP_DEBUG is disabled. Signed-off-by: Kever Yang

ram: rk3399: Mark existing prints via RAM_ROCKCHIP_DEBUG

2020-07-22T12:22:28Z

Right now all these debug statements are printing on the console to make sure proper dram initialization happens. Mark them into RAM_ROCKCHIP_DEBUG would be more meaningful and work like before since the RAM_ROCKCHIP_DEBUG is by default yet. No functionality changes.

ram: rk3399: Drop debug stride in driver

2020-07-22T12:22:23Z

stride debug is already present in sdram_common.c via RAM_ROCKCHIP_DEBUG. So, drop the redundant debug stride code in rk3399 driver. Signed-off-by: Jagan Teki Reviewed-by: Kever Yang

dtoc: extend dtoc to use struct driver_info when linking nodes

2020-07-10T04:00:29Z

In the current implementation, when dtoc parses a dtb to generate a struct platdata it converts the information related to linked nodes as pointers to struct platdata of destination nodes. By doing this, it makes difficult to get pointer to udevices created based on these information. This patch extends dtoc to use struct driver_info when populating information about linked nodes, which makes it easier to later get the devices created. In this context, reimplement functions like clk_get_by_index_platdata() which made use of the previous approach. Signed-off-by: Walter Lozano Reviewed-by: Simon Glass

drivers: rename drivers to match compatible string

2020-07-10T00:57:22Z

When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

ram: stm32mp1: add size and addr parameter to test all

2020-07-07T14:01:23Z

Add size and addr parameter to test "All" to override the default value (4kB and STM32_DDR_BASE) used in tests with these optional parameters: [size] or [addr]. When other optional parameters are present before [addr], they are replaced by default value: - [loop] = "1" - [pattern] = "-" (new: force default pattern) Example to use: DDR>test 0 1 0x20000 DDR>test 0 1 0x1000000 0xD0000000 Reviewed-by: Patrice Chotard Signed-off-by: Patrick Delaunay

ram: stm32mp1: use the DDR size by default in the test addressBus

2020-07-07T14:01:23Z

The test 4 = "AddressBus [size] [addr]" without parameter detects alias for any address bit only when: - size = real size of DDR - addr = start of DDR = 0xC0000000 These value must be the default value when parameters are absent. This patch sets bufsize to STM32_DDR_SIZE and get_bufsize() selects the correct value for bufsize when this parameter is absent = full size of the DDDR On EV1 board : DDR> test 4 running at 0xC0000000 length 0x40000000 On DK2 board DDR> test 4 running at 0xC0000000 length 0x20000000 Reviewed-by: Patrice Chotard Signed-off-by: Patrick Delaunay

ram: stm32mp1: add parameter addr in test FrequencySelectivePattern

Add a parameter addr in test FrequencySelectivePattern to select the base address used to execute the tests. Default value (when the parameter is absent) is STM32_DDR_BASE, selected in get_addr() function. Reviewed-by: Patrice Chotard Signed-off-by: Patrick Delaunay
