* ata: ahci: Don't cap AHCI port count under CONFIG_DM_SCSITuomas Tynkkynen2018-09-251-0/+2
| | | | | | | | When using device model this sort of hardcoded limits aren't used or necessary. Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Reviewed-by: Simon Glass <sjg@chromium.org>
* ata: ahci: Loop over the actual number of ports, not the maximumTuomas Tynkkynen2018-09-251-1/+1
| | | | | | | | | | | | The loop in ahci_start_ports() is looping over the maximum number of SCSI devices in the system, which can be larger than the amount of ports a particular AHCI controller has. The extra looping isn't directly harmful because the link_port_map bitmap won't have the bit set for a nonexistent port, but it is wasteful. Replace the loop limit with the port count of the AHCI controller instead. Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | The arm, xtensa and mips version of atomic.h were already very similar (the mips one was a copy of xtensa). Combine these implementations together to produce a generic atomic.h that can be included by these architectures (and any others that need it in future).

* dm: Update README.txt to clarify device tree usageTom Rini2018-09-251-0/+9
| | | | | | | | | | | | | | In the section about Device Trees add a paragraph at the end that clarifies how we decide of a tree is valid or not. We say that all bindings must either be in the specification (link provided) or in our device-tree-bindings directory. We say that most of these come from the Linux Kernel and as such some design decisions are made for us already, but that in most cases we wish to retain compatibility.

* board: ti: am335x: add support to fixup phy addressSekhar Nori2018-09-251-0/+78
| | | | | | | | | | | | | | | | | | | | On beaglebone black, it can so happen that PHY address is not latched correctly on reset and board boots with PHY responding to a different address than that programmed in device-tree. For example, see this report: https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J Workaround this by fixing up device-tree passed to kernel by using the PHY address detected in hardware. Beaglebone itself uses only one ethernet port and its DT currently uses phy_id (obsoleted). But the function has been written to handle multiple ports and phy_id as well as phy-handle to make the function more generically useful.

| | | | | | | | | | | | | | | | | | | | On some boards using TI CPSW, it may be possible that PHY address was not latched correctly, and the actual address that the phy responds on is different from that set in device-tree. For example, see this problem report on beaglebone black: https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J Add support to check for this condition and use the detected phy address when its safe to do so. Also, add a public API that exposes the phy address of a given slave. This can be used to update device-tree that is passed to Linux kernel.

* spl: Weed out CONFIG_SYS_TEXT_BASE usageMarek Vasut2018-09-2511-20/+30
| | | | | | | | | | | | | | | | | | | | | The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location is available and can be corrupted by loading ie. uImage or fitImage headers there. Sometimes it could be beneficial to load the headers elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we still want to parse the image headers in some local onchip memory to ie. extract firmware from that image. Add the possibility to override the location where the headers get loaded by introducing new function, spl_get_load_buffer() which takes two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the data that are to be loaded there -- and returns a valid buffer address or hangs the system. The default behavior is the same as before, add the offset to CONFIG_SYS_TEXT_BASE and return that address. User can override the weak spl_get_load_buffer() function though.
