From 5fef24c912a44a08ab644aa16ceb5a435491f9d9 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 30 Jun 2020 12:08:58 +0200 Subject: mips: octeon: Add minimal Octeon 3 EBB7304 EVK support This patch adds very basic minimal support for the Marvell Octeon 3 CN73xx based EBB7304 EVK. Please note that the basic Octeon port does not support DDR3/4 initialization yet. To still use U-Boot on with this port, the L2 cache (4MiB) is used as RAM. This way, U-Boot can boot to the prompt on this board. Supported devices: - UART - reset - CFI parallel NOR flash Signed-off-by: Stefan Roese --- include/configs/octeon_common.h | 19 +++++++++++++++++++ include/configs/octeon_ebb7304.h | 20 ++++++++++++++++++++ 2 files changed, 39 insertions(+) create mode 100644 include/configs/octeon_common.h create mode 100644 include/configs/octeon_ebb7304.h (limited to 'include') diff --git a/include/configs/octeon_common.h b/include/configs/octeon_common.h new file mode 100644 index 00000000000..530f02ad3cb --- /dev/null +++ b/include/configs/octeon_common.h @@ -0,0 +1,19 @@ +/* SPDX-License-Identifier: GPL-2.0+ */ +/* + * Copyright (C) 2019-2020 + * Marvell + */ + +#ifndef __OCTEON_COMMON_H__ +#define __OCTEON_COMMON_H__ + +/* No DDR init yet -> run in L2 cache with limited resources */ +#define CONFIG_SYS_MALLOC_LEN (256 << 10) +#define CONFIG_SYS_SDRAM_BASE 0xffffffff80000000 +#define CONFIG_SYS_MONITOR_BASE CONFIG_SYS_TEXT_BASE + +#define CONFIG_SYS_LOAD_ADDR (CONFIG_SYS_SDRAM_BASE + (1 << 20)) + +#define CONFIG_SYS_INIT_SP_OFFSET 0x180000 + +#endif /* __OCTEON_COMMON_H__ */ diff --git a/include/configs/octeon_ebb7304.h b/include/configs/octeon_ebb7304.h new file mode 100644 index 00000000000..04fe4dfe22e --- /dev/null +++ b/include/configs/octeon_ebb7304.h @@ -0,0 +1,20 @@ +/* SPDX-License-Identifier: GPL-2.0+ */ +/* + * Copyright (C) 2019-2020 + * Marvell + */ + +#ifndef __CONFIG_H__ +#define __CONFIG_H__ + +#include "octeon_common.h" + +/* + * CFI flash + */ +#define CONFIG_SYS_MAX_FLASH_BANKS 1 +#define CONFIG_SYS_MAX_FLASH_SECT 256 +#define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_8BIT +#define CONFIG_SYS_FLASH_EMPTY_INFO /* flinfo indicates empty blocks */ + +#endif /* __CONFIG_H__ */ -- cgit v1.2.3
