Subject: [U-Boot] [PATCH v4 0/4] arm: aspeed: Basic support for Aspeed AST2500 part and eval board
Date: Wed, 18 Jan 2017 13:44:54 -0800 [thread overview]
Message-ID: <20170118214458.51081-1-maxims@google.com> (raw)
In-Reply-To: <20170111234513.45760-1-maxims@google.com>
This series adds minimal support for AST2500 part and eval board,
enough to boot EVB into prompt. It contains WDT, Timer, Sysreset,
Clock (very basic) and SDRAM MC drivers, all written from scratch,
using AST2500 datasheet. Aspeed's SDK was used only for reference.
Given very limited documentation provided by Aspeed, some parts of SDRAM
init sequence were basically rewritten to do the same thing that is done
in Aspeed SDK, without real understanding of what is going on.
The file layout closely follows the example of rk3288 chip and firefly-rk3288
board.
Changes in v4:
- Expanded AST2500 description in Kconfig
- Expanded ast_timer description in Kconfig
- Added struct ast_timer_counter to timer private data
- Use dev_get_addr_ptr in timer's of_platdata
- Added helper function to wdt for resetting peripherals
- Expanded AST2500 EVB description in Kconfig
- Added docstrings for ast_get_clk() and ast_get_scu()
- Fixed include file ordering
- Added docstring for ast2500_get_uart_clk_rate
- Use dev_get_addr_ptr
- Use WDT helper function to reset memory controller
- Fixed include file order in ast2500-board.c
- Multiple cosmetic changes: new lines, removed parens etc.
- Removed local PRE_CON_RAM_SZ variable from aspeed-common.h
- Cosmetic: Fixed comment formatting
Changes in v3:
- Added SYS_TEXT_BASE as Kconfig option
- Removed CONFIG_SYS_TEXT_BASE in favor of Kconfig option
- In aspeed-common.h changed some options from define CONFIG_FOO 1 to
define CONFIG_FOO
- In evb_ast2500.h fixed some options to define CONFIG_FOO instead of
define CONFIG_FOO 1
Changes in v2:
- Moved number of WDTs to a Kconfig option
Changes in v1:
- Merged together the patches related to aspeed common drivers and
configuration
- Fixed timer driver name (was sandbox_timer)
- Removed yet nonexistent files from mach-aspeed/Makefile
- Merge together all patches related to ast2500 specific drivers
- Add Copyright statement to all c/h files
- Use DT include from Linux Kernel, Add U-Boot specific modifications in
ast2500-u-boot.dtsi
- Merge together all patches related to ast2500 boards common
functions/configs
- Add copyright statement to ast2500-board.c
- Merge together patches related to ast2500 eval board configuration
- Add Copyright statement to evb_ast2500.c
- Use ast2500-u-boot.dtsi instead of ast2500.dtsi, which is now Linux
Kernel DT Include
Maxim Sloyko (4):
aspeed: Add drivers common to all Aspeed SoCs
aspeed: Add basic ast2500-specific drivers and configuration
aspeed: Board init functions and common configs for ast2500 based
boards
aspeed: Support for ast2500 Eval Board
