From c153576d8dfc80c651a7edb046adbaa1c1c17e42 Mon Sep 17 00:00:00 2001 From: Tony Dinh Date: Thu, 3 Feb 2022 14:32:29 -0800 Subject: [PATCH] arm: kirkwood: Dockstar : Add DM Ethernet The Dockstar board has the network chip Marvell 88E1116R. Convert to Ethernet driver model, and use uclass mvgbe and the compatible driver M88E1118R to bring up Ethernet. - Add CONFIG_DM_ETH and associated configs. - Add board_eth_init() to use uclass mvgbe to bring up the network. And remove ad-hoc code. - Add CONFIG_PHY_MARVELL to properly configure the network. - Currently, CONFIG_RESET_PHY_R symbol is used in arch/arm/mach-kirkwood/include/mach/config.h for all Kirkwood boards with mv8831116 PHY, with each board defines the function reset_phy(). Undefine it for this board. - Miscellaneous changes: Move constants to .c file and remove header file board/Seagate/dockstar/dockstar.h, use CONFIG_SYS_THUMB_BUILD to keep u-boot image under 512K, add CONFIG_HUSH_PARSER, use BIT macro, and cleanup comments. - Note: This patch is a RESEND for a previous patch: https://patchwork.ozlabs.org/project/uboot/patch/20210812051854.1340-2-mibodhi@gmail.com/ Signed-off-by: Tony Dinh Reviewed-by: Stefan Roese --- board/Seagate/dockstar/dockstar.c | 62 +++++++++++++-------------------------- board/Seagate/dockstar/dockstar.h | 27 ----------------- configs/dockstar_defconfig | 5 ++++ include/configs/dockstar.h | 20 ++++--------- 4 files changed, 30 insertions(+), 84 deletions(-) delete mode 100644 board/Seagate/dockstar/dockstar.h diff --git a/board/Seagate/dockstar/dockstar.c b/board/Seagate/dockstar/dockstar.c index fb69193..d72e3ef 100644 --- a/board/Seagate/dockstar/dockstar.c +++ b/board/Seagate/dockstar/dockstar.c @@ -1,5 +1,6 @@ // SPDX-License-Identifier: GPL-2.0+ /* + * Copyright (C) 2022 Tony Dinh * Copyright (C) 2010 Eric C.
