* riscv : serial: use rx watermark to indicate rx data is presentSagar Shrikant Kadam2019-08-151-16/+7
| | | | | | | | | | | | | | | | | | In y-modem transfer mode, tstc/getc fail to check if there is any data available / received in RX FIFO, and so y-modem transfer never succeeds. Using receive watermark bit within ip register fixes the issue. This patch is based on commit c7392b7bc4e1 ("Use the RX watermark interrupt pending bit for TSTC") available at[1] [1] https://github.com/sifive/HiFive_U-Boot/tree/regression Signed-off-by: Sagar Shrikant Kadam <sagar.kadam@sifive.com> Reviewed-by: Anup Patel <anup.patel@wdc.com> Tested-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Padmarao Begari <padmarao.begari@microchip.com> Tested-by: Padmarao Begari <padmarao.begari@microchip.com>

| * pci: pci_mvebu: set BAR0 after memory space is setMarek Behún2019-08-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The non-DM version of this driver used to set BAR0 register after the calls to pci_set_region. I found out that for some strange reason the ath10k driver in kernel fails to work if this is done the other way around. I know that Linux's driver should not depend on how U-Boot does things, but for some strange reason it does and this seems to be the simplest solution. Fix it since it caused regressions on Omnia.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new SERDES driver for TI's AM654x SoC which configures the SERDES only for PCIe. Support fo USB3 can be added later. SERDES in am654x has three input clocks (left input, external reference clock and right input) and two output clocks (left output and right output) in addition to a PLL mux clock which the SERDES uses for Clock Multiplier Unit (CMU refclock). The PLL mux clock can select from one of the three input clocks. The right output can select between left input and external reference clock while the left output can select between the right input and external reference clock. The driver has support to select PLL mux and left/right output mux as specified in device tree. Signed-off-by: Sekhar Nori <nsekhar@ti.com>

The following compile warning is removed: ===================== WARNING ====================== This board does not use CONFIG_WDT (DM watchdog support). Please update the board to use CONFIG_WDT before the v2019.10 release. Failure to update by the deadline may result in board removal. See doc/driver-model/MIGRATION.txt for more info. ==================================================== CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices after DT/DM conversion, adjusted kconfig accordingly. DM watchdog support is enabled by default in SPL. The SPL image doesn't fit into SRAM because of size constraints and build breaks with an overflow. For this reason DM watchdog support should be disabled in SPL, driver code should be adjusted accordingly to serve this purpose.
