Author: adrian Date: Thu Dec 24 18:40:10 2015 New Revision: 292703 URL: https://svnweb.freebsd.org/changeset/base/292703 Log: [rt305x] Add initial RT5350 and MT7620 glue. * Add in chipset awareness to the obio bus layout (ie, which devices are where); * Add in some USB OTG changes to be aware of the newer stuff; * Add in a configurable primary console - some chips use the normal UART, some use UARTLITE. Tested (by Stanislav); * RT3050 (NFS) * RT5350 (NFS, MFS) * MT7620 (USB) Submitted by: Stanislav Galabov <sgalabov@gmail.com> Modified: head/sys/mips/rt305x/files.rt305x head/sys/mips/rt305x/obio.c head/sys/mips/rt305x/rt305x_dotg.c head/sys/mips/rt305x/rt305x_machdep.c head/sys/mips/rt305x/rt305x_sysctl.c head/sys/mips/rt305x/uart_bus_rt305x.c head/sys/mips/rt305x/uart_cpu_rt305x.c Modified: head/sys/mips/rt305x/files.rt305x ============================================================================== --- head/sys/mips/rt305x/files.rt305x Thu Dec 24 18:36:08 2015 (r292702) +++ head/sys/mips/rt305x/files.rt305x Thu Dec 24 18:40:10 2015 (r292703) @@ -9,6 +9,11 @@ mips/rt305x/rt305x_gpio.c optional gpio mips/rt305x/uart_bus_rt305x.c optional uart mips/rt305x/uart_cpu_rt305x.c optional uart mips/rt305x/uart_dev_rt305x.c optional uart +mips/rt305x/rt305x_dotg.c optional dwcotg +mips/rt305x/rt305x_ehci.c optional ehci +mips/rt305x/rt305x_ohci.c optional ohci +mips/rt305x/rt305x_spi.c optional spibus +mips/rt305x/rt305x_pci.c optional pci mips/mips/intr_machdep.c standard mips/mips/tick.c standard dev/rt/if_rt.c optional rt Modified: head/sys/mips/rt305x/obio.c ============================================================================== --- head/sys/mips/rt305x/obio.c Thu Dec 24 18:36:08 2015 (r292702) +++ head/sys/mips/rt305x/obio.c Thu Dec 24 18:40:10 2015 (r292703) @@ -221,10 +221,10 @@ obio_attach(device_t dev) obio_add_res_child(dev, "pcm", 0, PCM_BASE, (PCM_END - PCM_BASE + 1), IC_PCM); +#endif obio_add_res_child(dev, "uart", 0, UART_BASE, (UART_END - UART_BASE + 1), IC_UART); -#endif obio_add_res_child(dev, "gpio", 0, PIO_BASE, (PIO_END - PIO_BASE + 1), IC_PIO); @@ -241,19 +241,28 @@ obio_attach(device_t dev) obio_add_res_child(dev, "i2s", 0, I2S_BASE, (I2S_END - I2S_BASE + 1), IC_I2S); +#endif obio_add_res_child(dev, "spi", 0, SPI_BASE, (SPI_END - SPI_BASE + 1), -1); -#endif obio_add_res_child(dev, "uart", 1, UARTLITE_BASE, (UARTLITE_END - UARTLITE_BASE + 1), IC_UARTLITE); +#if !defined(RT5350) && !defined(MT7620) obio_add_res_child(dev, "cfi", 0, FLASH_BASE, (FLASH_END - FLASH_BASE + 1), -1); - obio_add_res_child(dev, "dotg", 0, + obio_add_res_child(dev, "dwcotg", 0, USB_OTG_BASE, (USB_OTG_END - USB_OTG_BASE + 1), IC_OTG); +#else + obio_add_res_child(dev, "ehci", 0, + USB_OTG_BASE, (USB_OTG_END - USB_OTG_BASE + 1), + IC_OTG); + obio_add_res_child(dev, "ohci", 0, + USB_OHCI_BASE, (USB_OHCI_END - USB_OHCI_BASE + 1), + IC_OTG); +#endif obio_add_res_child(dev, "switch", 0, ETHSW_BASE, (ETHSW_END - ETHSW_BASE + 1), IC_ETHSW); Modified: head/sys/mips/rt305x/rt305x_dotg.c ============================================================================== --- head/sys/mips/rt305x/rt305x_dotg.c Thu Dec 24 18:36:08 2015 (r292702) +++ head/sys/mips/rt305x/rt305x_dotg.c Thu Dec 24 18:40:10 2015 (r292703) @@ -2,6 +2,7 @@ __FBSDID("$FreeBSD$"); /*- + * Copyright (c) 2015 Stanislav Galabov.
