From 8d67c3685e3b4bea8524e2e25b1443b62a69352b Mon Sep 17 00:00:00 2001 From: Shengzhou Liu Date: Wed, 5 Mar 2014 15:04:48 +0800 Subject: powerpc/t2080rdb: Add T2080PCIe-RDB board support T2080PCIe-RDB is a Freescale Reference Design Board that hosts the T2080 SoC. It works in two mode: standalone mode and PCIe endpoint mode. T2080PCIe-RDB Feature Overview ------------------------------ Processor: - T2080 SoC integrating four 64-bit dual-threads e6500 cores up to 1.8GHz DDR Memory: - Single memory controller capable of supporting DDR3 and DDR3-LP devices - 72bit 4GB DDR3-LP SODIMM in slot Ethernet interfaces: - Two 10M/100M/1G RGMII ports on-board - Two 10Gbps SFP+ ports on-board - Two 10Gbps Base-T ports on-board Accelerator: - DPAA components consist of FMan, BMan, QMan, PME, DCE and SEC SerDes 16 lanes configuration: - SerDes-1 Lane A-B: to two 10G XFI fiber (MAC9 & MAC10) - SerDes-1 Lane C-D: to two 10G Base-T (MAC1 & MAC2) - SerDes-1 Lane E-H: to PCIe Goldfinger (PCIe4 x4, Gen3) - SerDes-2 Lane A-D: to PCIe Slot (PCIe1 x4, Gen2) - SerDes-2 Lane E-F: to C293 secure co-processor (PCIe2 x2) - SerDes-2 Lane G-H: to SATA1 & SATA2 IFC/Local Bus: - NOR: 128MB 16-bit NOR flash - NAND: 512MB 8-bit NAND flash - CPLD: for system controlling with programable header on-board eSPI: - 64MB N25Q512 SPI flash USB: - Two USB2.0 ports with internal PHY (both Type-A) PCIe: - One PCIe x4 gold-finger - One PCIe x4 connector - One PCIe x2 end-point device (C293 Crypto co-processor) SATA: - Two SATA 2.0 ports on-board SDHC: - support a TF-card on-board I2C: - Four I2C controllers. UART: - Dual 4-pins UART serial ports Signed-off-by: Shengzhou Liu Reviewed-by: York Sun --- board/freescale/t208xrdb/cpld.c | 71 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 board/freescale/t208xrdb/cpld.c (limited to 'board/freescale/t208xrdb/cpld.c') diff --git a/board/freescale/t208xrdb/cpld.c b/board/freescale/t208xrdb/cpld.c new file mode 100644 index 0000000000..4aa126be54 --- /dev/null +++ b/board/freescale/t208xrdb/cpld.c @@ -0,0 +1,71 @@ +/* + * Copyright 2014 Freescale Semiconductor + * + * SPDX-License-Identifier: GPL-2.0+ + * + * Freescale T2080RDB board-specific CPLD controlling supports. + */ + +#include +#include +#include "cpld.h" + +u8 cpld_read(unsigned int reg) +{ + void *p = (void *)CONFIG_SYS_CPLD_BASE; + + return in_8(p + reg); +} + +void cpld_write(unsigned int reg, u8 value) +{ + void *p = (void *)CONFIG_SYS_CPLD_BASE; + + out_8(p + reg, value); +} + +/* Set the boot bank to the alternate bank */ +void cpld_set_altbank(void) +{ + u8 reg = CPLD_READ(flash_csr); + + reg = (reg & ~CPLD_BANK_SEL_MASK) | CPLD_LBMAP_ALTBANK; + CPLD_WRITE(flash_csr, reg); + CPLD_WRITE(reset_ctl, CPLD_LBMAP_RESET); +} + +/* Set the boot bank to the default bank */ +void cpld_set_defbank(void) +{ + u8 reg = CPLD_READ(flash_csr); + + reg = (reg & ~CPLD_BANK_SEL_MASK) | CPLD_LBMAP_DFLTBANK; + CPLD_WRITE(flash_csr, reg); + CPLD_WRITE(reset_ctl, CPLD_LBMAP_RESET); +} + +int do_cpld(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) +{ + int rc = 0; + + if (argc <= 1) + return cmd_usage(cmdtp); + + if (strcmp(argv[1], "reset") == 0) { + if (strcmp(argv[2], "altbank") == 0) + cpld_set_altbank(); + else + cpld_set_defbank(); + } else { + rc = cmd_usage(cmdtp); + } + + return rc; +} + +U_BOOT_CMD( + cpld, CONFIG_SYS_MAXARGS, 1, do_cpld, + "Reset the board or alternate bank", + "reset: reset to default bank\n" + "cpld reset altbank: reset to alternate bank\n" +); -- cgit v1.2.3
