This series update SiFive Unleashed clock driver and Cadence MACB driver so that: 1. It is in sync with upstream Linux driver 2. It uses latest DT bindings as-per upstream Linux driver

With this series, we can now use latest DT bindings with U-Boot. I have tested SiFive Serial driver and Cadence MACB ethernet driver with this changes and both work fine.

The legacy FSBL will still pass DTB with older DT bindings which will break the updated SiFive Unleashed clock driver. To tackle this, we have embedded DTB in OpenSBI FW_PAYLOAD firmware for SiFive Unleashed so that OpenSBI will override and pass updated DTB to U-Boot.

The updated DTB passed by OpenSBI is in fact the DTB build by upstream Linux so we can straight away pass this DTB to Linux as well.

This series can be found in riscv_unleashed_clk_sync_v11 branch at: https://github.com/avpatel/u-boot.git

To try this series use latest OpenSBI at: https://github.com/riscv/opensbi.git And Linux-5.3-rc1 from v5.3-rc1_unleashed branch at: https://github.com/avpatel/linux.git

Changes since v10: - Addressed comments from Joe on MACB driver changes

Changes since v9: - Remove all accepted and merged patches except MACB driver patches - Rebased MACB driver patches upon v2 patches from Ramon Fried (Refer, https://www.mail-archive.com/u-boot@lists.denx.de/msg334300.html) - Added separate patch to sync-up SiFive Unleashed config header with QEMU RISC-V virt machine config header - Added separate patch for more updates to SiFive Unleashed README

Changes since v8: - Removed probe() from macb_config for PATCH6 - Renamed set_tx_clk() to clk_init() in macb_config for PATCH6

Changes since v7: - Update PATCH6 to not treat dma_burst_length = 0 as skip gmac_configure_dma() - Update PATCH9 to check endianess at runtime

Changes since v6: - Added separate patch to fix endianess check in gmac_configure_dma()

Changes since v5: - Addressed Ramon's comments in PATCH6 - Addressed Bin's comments in PATCH7

Changes since v4: - Rebased patches upon Ramon's MACB changes (Refer, https://patchwork.ozlabs.org/patch/1114025/) - Added PATCH7 to setup ethaddr based on board serial number read from OTP - Added PATCH8 to update documentation

Changes since v3: - Extend MACB ethernet driver for SiFive Unleashed board (just like Linux)

Changes since v2: - Dropped PATCH6 which adds new compatible string to MACB driver because more changes are required in MACB driver for different ethernet speeds

Changes since v1: - Dropped GEMGXL clock driver - Added new compatible string for SiFive MACB ethernet

New subject: [U-Boot] [PATCH v11 1/4] 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.

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.

New subject: [U-Boot] [PATCH v11 3/4] riscv: sifive: fu540: Sync-up config header with RISC-V QEMU support

We typically use same set of distro images (yocto, debian, fedora, etc.) on both QEMU RISC-V virt machine and SiFive Unleashed board.

With growing kernel and ramdisk images, we need to re-adjust default U-Boot environment variables. The config header for QEMU RISC-V virt machine has been already updated to handle bigger kernel and ramdisk images hence this patch updates SiFive FU540 config header accordingly.

New subject: [U-Boot] [PATCH v11 4/4] doc: sifive-fu540: Update README to explicitly load DTB for Linux

We should explicitly load DTB from TFTP server or MMC/SD card for Linux booting. This will allow us: 1. To use different Linux DTB for SiFive Unleashed board with expansion board connected. 2. Avoid re-flashing OpenSBI firmware whenever board connections change.

This patch updates reference bootlog in SiFive FU540 README as-per above.
