2023-10-13treewide: use dev_read_addr_*_ptr() where appropriateMatthias Schiffer1-10/+10
A follow-up to commit 842fb5de424e ("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer") and commit 320a1938b6f7 ("drivers: use devfdt_get_addr_index_ptr when cast to pointer"). In addition to using the *_ptr variants of these functions where the address is cast to a pointer, this also changes devfdt_get_addr_*() to dev_read_addr_*() in a few places. Some variable and field types are changed from fdt_addr_t or phys_addr_t to void* where the cast was happening later. This patch fixes a number of compile warnings when building a 32bit U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error handling where the return value of dev_read_addr() etc. was checked for NULL instead of FDT_ADDR_T_NONE.

2023-04-24arm: mach-k3: Move sdelay() and wait_on_value() declarationAndrew Davis1-0/+4
These probably should be in some system wide header given their use. Until then move them out of K3 sys_proto.h so we can finish cleaning that header out. Signed-off-by: Andrew Davis <afd@ti.com> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-10-25ram: k3-am654: Do not rely on default values for certain DDR registerJames Doublesin1-7/+48
Added the following registers to the DDR configuration: - ACIOCR0, - ACIOCR3, - V2H_CTL_REG, - DX8SLxDQSCTL. Modified enable_dqs_pd and disable_dqs_pd to only touch the associated bit fields for pullup and pulldown registers (to preserve slew rate and other bits in that same register). Also update the dts files in the same patch to maintain git bisectability. Signed-off-by: James Doublesin <doublesin@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

2018-11-16ram: Introduce K3 AM654 DDR Sub System driverLokesh Vutla1-0/+825
K3 based AM654 devices has DDR memory subsystem that comprises Synopys DDR controller, Synopsis DDR phy and wrapper logic to intergrate these blocks into the device. This DDR subsystem provides an interface to external SDRAM devices. Adding support for the initialization of the external SDRAM devices by configuring the DDRSS registers and using the buitin PHY routines.
