ram: stm32: add stm32h7 support

2017-07-26T15:29:15Z

STM32F7 and H7 shared the same SDRAM control block. On STM32H7 few control bits has been added. The current driver need some minor adaptation as FMC block enable/disable for H7. Signed-off-by: Patrice Chotard

ram: stm32: add second SDRAM bank management

2017-07-26T15:29:15Z

FMC is able to manage 2 SDRAM banks, but the current driver implementation is only able to manage the first SDRAM bank. Even if only bank2 is used, some bank1 registers must be configured. Signed-off-by: Patrice Chotard Reviewed-by: Simon Glass

ram: stm32: replace fdtdec_get by ofnode calls

2017-07-26T15:29:14Z

Replace all fdtdec_get..() calls by ofnode_read...() or dev_read..(). This will allow drivers to support a live device tree. Signed-off-by: Patrice Chotard Reviewed-by: Simon Glass

ram: stm32: get base address from DT

2017-07-26T15:29:14Z

Retrieve RAM base address from DT instead of using STM32_SDRAM_FMC For STM32F7, FMC block base address is 0xA0000000, but SDRAM registers are located at offset 0x140 inside FMC block. Update the stm32_fmc_regs fields with all FMC registers to map SDRAM registers at the right address. These additionals registers will be used later. Signed-off-by: Patrice Chotard

ram: stm32: migrate fmc defines in driver file

2017-07-26T15:29:07Z

Migrate all FMC defines from arch/arm/include/asm/arch-stm32f7/fmc.h to drivers/ram/stm32_sdram.c This will avoid to add an additionnal arch-stm32xx/fmc.h file when a new stm32 family soc will be introduced. Signed-off-by: Patrice Chotard Reviewed-by: Vikas Manocha Reviewed-by: Simon Glass

drivers: ram: stm32: fix compilation issue

2017-06-05T18:13:13Z

If CONFIG_CLK flag is not set, compilation raises the following error message: drivers/ram/stm32_sdram.c: In function 'stm32_fmc_probe': drivers/ram/stm32_sdram.c:154:2: error: 'ret' undeclared (first use in this function) ret = stm32_sdram_init(dev); Signed-off-by: Patrice Chotard cc: Vikas Manocha

dm: core: Replace of_offset with accessor (part 2)

2017-06-01T13:03:04Z

At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function. Signed-off-by: Simon Glass

dm: Rename dev_addr..() functions

2017-06-01T13:03:01Z

These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file. Signed-off-by: Simon Glass

dm: Use dm.h header when driver mode is used

2017-06-01T12:57:52Z

This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass
