Subject: [PATCH 02/21] net: macb: sync header definitions as taken from Linux
Few registers and bits were added by Cadence and
they were not updated in the headers.
Take the latest definitions as defined in Linux
header (5.1) that also includes some comments
about existing registers.
One register was improperly named (UR), fix that.

Subject: [PATCH 11/21] clk: sifive: Sync-up main driver with upstream Linux
The DT bindings of SiFive clock driver in upstream Linux has
changes. As-per latest DT bindings, the clock driver takes two
parent clocks and compatible string has also changed.
This patch sync-up SiFive clock driver implementation as-per
upstream Linux so that we now use latest DT bindings.

Subject: [PATCH 12/21] clk: sifive: Drop GEMGXL clock driver
The GEMGXL clock driver is now directly part of Cadence MACB
ethernet driver in upstream Linux kernel. There is no separate
GEMGXL clock driver in upstream Linux kernel hence we drop
GEMGXL clock driver from U-Boot as well.

Subject: [PATCH 13/21] net: macb: Extend MACB driver for SiFive Unleashed
board
The SiFive MACB ethernet has a custom TX_CLK_SEL register to select
different TX clock for 1000mbps vs 10/100mbps.
This patch adds SiFive MACB compatible string and extends the MACB
ethernet driver to change TX clock using TX_CLK_SEL register for
SiFive MACB.

Subject: [PATCH 15/21] doc: sifive-fu540: Update README for steps to create
FW_PAYLOAD
Due changes in DT bindings, we now embed DTB from Linux-5.3 (or
higher) in OpenSBI FW_PAYLOAD along with payload u-boot.bin. This
patch updates SiFive FU540 README to reflect the changes in build
and boot steps.

Subject: [PATCH 16/21] net: macb: Fix check for little-endian system in
gmac_configure_dma()
Instead of depending on CONFIG_SYS_LITTLE_ENDIAN, we check at runtime
whether underlying system is little-endian or big-endian. This way
we are not dependent on any U-Boot specific OR compiler specific macro
to check system endianness.

Subject: [PATCH 17/21] spi: Add SiFive SPI driver
This patch adds SiFive SPI driver. The driver is 100% DM driver
and it determines input clock using clk framework.
The SiFive SPI block is found on SiFive FU540 SOC and is used to
access flash and MMC devices on SiFive Unleashed board.
This driver implementation is inspired from the Linux SiFive SPI
driver available in Linux-5.2 or higher and SiFive FSBL sources.

Subject: [PATCH 18/21] mmc: skip select_mode_and_width for MMC SPI host
The MMC mode and width are fixed for MMC SPI host hence we skip
sd_select_mode_and_width() and mmc_select_mode_and_width() for
MMC SPI host.

Subject: [PATCH] net: macb: Extend MACB driver for SiFive Unleashed board
The SiFive MACB ethernet has a custom TX_CLK_SEL register to select
different TX clock for 1000mbps vs 10/100mbps.
This patch adds SiFive MACB compatible string and extends the MACB
ethernet driver to change TX clock using TX_CLK_SEL register for
SiFive MACB.
