For the RK3188, the BROM will attempt to load up the first stage image (SPL for the RK3188) in two steps: first 1KB to offset 0x800 in the SRAM and then the remainder to offset 0xc00 in the SRAM. It always enters at 0x804, though. With this changeset, the RK3188 boot removes the TPL (stub) stage and builds a single SPL binary that utilizes the early back-to-bootrom via the boot0-hook. Consequently, the passing of the saved boot params via pmu->os_reg[2] is also removed. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> |

# # Xilinx ZYNQ U-Boot # # (C) Copyright 2013 Xilinx, Inc. # # SPDX-License-Identifier: GPL-2.0+ # 1. About this This document describes the information about Xilinx Zynq U-Boot - like supported boards, ML status and TODO list. 2. Zynq boards Xilinx Zynq-7000 All Programmable SoCs enable extensive system level differentiation, integration, and flexibility through hardware, software, and I/O programmability. * zc702 (single qspi, gem0, mmc) [1] * zc706 (dual parallel qspi, gem0, mmc) [2] * zed (single qspi, gem0, mmc) [3] * microzed (single qspi, gem0, mmc) [4] * zc770 - zc770-xm010 (single qspi, gem0, mmc) - zc770-xm011 (8 or 16 bit nand) - zc770-xm012 (nor) - zc770-xm013 (dual parallel qspi, gem1) 3. Building ex. configure and build for zc702 board $ make zynq_zc702_config $ make 4. Bootmode Zynq has a facility to read the bootmode from the slcr bootmode register once user is setting through jumpers on the board - see page no:1546 on [5] All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins on [5]. board_late_init() will read the bootmode values using slcr bootmode register at runtime and assign the modeboot variable to specific bootmode string which is intern used in autoboot. SLCR bootmode register Bit[3:0] values #define ZYNQ_BM_NOR 0x02 #define ZYNQ_BM_SD 0x05 #define ZYNQ_BM_JTAG 0x0 "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot" bootmode strings at runtime. 5. Mainline status - Added basic board configurations support. - Added zynq u-boot bsp code - arch/arm/cpu/armv7/zynq - Added zynq boards named - zc70x, zed, microzed, zc770_xm010, zc770_xm012, zc770_xm013 - Added zynq drivers: serial - drivers/serial/serial_zynq.c net - drivers/net/zynq_gem.c mmc - drivers/mmc/zynq_sdhci.c mmc - drivers/mmc/zynq_sdhci.c spi- drivers/spi/zynq_spi.c i2c - drivers/i2c/zynq_i2c.c - Done proper cleanups on board configurations - Added basic FDT support for zynq boards - d-cache support for zynq_gem.c 6. TODO - Add zynq boards support - zc770_xm011 - Add zynq qspi controller driver - Add zynq nand controller driver - Add FDT support on individual drivers [1] http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC702-G.htm [2] http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC706-G.htm [3] http://zedboard.org/product/zedboard [4] http://zedboard.org/product/microzed [5] http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf -- Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Sun Dec 15 14:52:41 IST 2013
