2019-05-03board: am335x: Drop duplicate pinmux configurationPaul Barker
In commit ad6054f1fe128f797b6eb2964afca6674b584785 where support for the Sancloud BeagleBone Enhanced (BBE) was added, new conditional configuration of either MII pin muxing or RGMII pin muxing is done depending on the board type. However, the old call to set up MII pin muxing was not removed. This may result in misconfiguration of the pin muxing for the BBE or duplicate configuration for other boards and so we remove this obsolete call.

2018-12-10ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPLJean-Jacques Hiblot
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT when all I2C "clients" have been migrated to use the DM API. This a step in that direction for the TI based platforms.

2018-09-25board: ti: am335x: add support to fixup phy addressSekhar Nori
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.

2018-07-25efi_loader: Rename sections to allow for implicit dataAlexander Graf
Some times gcc may generate data that is then used within code that may be part of an efi runtime section. That data could be jump tables, constants or strings. In order to make sure we catch these, we need to ensure that gcc emits them into a section that we can relocate together with all the other efi runtime bits. This only works if the -ffunction-sections and -fdata-sections flags are passed and the efi runtime functions are in a section that starts with ".text". Up to now we had all efi runtime bits in sections that did not interfere with the normal section naming scheme, but this forces us to do so. Hence we need to move the efi_loader text/data/rodata sections before the global *(.text*) catch-all section. With this patch in place, we should hopefully have an easier time to extend the efi runtime functionality in the future. Signed-off-by: Alexander Graf <agraf@suse.de> [agraf: Fix x86_64 breakage]
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

It's useful when we have several devices (in fastboot mode) connected to single host and want to choose which one to flash. We can't use omap_die_id_serial() for this, because AM335x lacks DIE_ID, as can be seen from AM335x TRM.
