2021-01-28bayhub bh720: Factor out common HS200 init codeAngel Pons
Except for one debug print in sarien, both functions are identical. Move them to driver code to avoid unnecessary redundancy.

2019-10-22AUTHORS: Move src/drivers/[a*-i*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2019-10-04devicetree: Fix improper use of chip_operationsKyösti Mälkki
Auto-discoverable PCI devices do not require field .enable_dev of chip_operations to be set. They are matched with PCI drivers by the use of PCI vendor and device ID fields. The name given for the chip_operations struct must match the pathname the way it is present in the devicetree.cb files. If there was no match, util/sconfig would currently choose to use the empty weak declaration it creates in static.c file.

2018-09-28src/*: normalize Google copyright headersPatrick Georgi
As per internal discussion, there's no "ChromiumOS Authors" that's meaningful outside the Chromium OS project, so change everything to the contemporary "Google LLC." While at it, also ensure consistency in the LLC variants (exactly one trailing period). "Google Inc" does not need to be touched, so leave them alone.

2018-08-28google/grunt: Reset BayHub EMMC freq to SD base CLK 50MHzKevin Chiu
Bayhub eMMC controller default runs SD base 50MHz at the first power on. After boot into OS, mmc kernel driver will config controller to HS200/208MHz and send MMC CMD21 (tuning block). But Bayhub PCR register 0x3E4[22] (eMMC MODE select) is not clear after system warm reset. So eMMC will still run 208Mhz but there is no block tuning cmd in depthcharge. It will cause two Sandisk eMMC (SDINBDA4-64G-V/SDINBDA4-32G-V) to fail to load kernel and trap in 0x5B error (No bootable kernel found on disk).

2018-06-25mb/google/kahlee/variants/grunt: Select low-power mode for BayHub720Simon Glass
Put the PCIe clock pins in power-saving mode for the BayHub eMMC bridge to save power. This requires use of an additional register (Misc control register 2) and another bit in the existing 'protect' register. The naming of bit 0 of that register is incorrect, based on the latest datasheet (14 June 2018) so fix that too.
