[U-Boot] [PATCH 0/1] tegra2: move tegra2 SoC code to arch/arm/cpu/tegra2-common
by Allen Martin 10 Jun '12

10 Jun '12

This is part of an upcoming patch set to move all armv4t code out of tegra2 u-boot and put it into an SPL, but I wanted to get some early feedback on this patch. This moves most of the tegra2 SoC code from arch/arm/cpu/armv7 to a new directory arch/arm/cpu/tegra2-common. This code will be shared between the armv7 and armv4t builds of tegra2. -Allen nvpublic

This program sends this boot message until +it receives a positive acknowledgement. The image is transfered using +Xmodem. + +Additionally, this program implements a minimal terminal mode, which +can be used either standalone, or entered immediately following boot +image transfer completion.

[U-Boot] Which version of u-boot contains support for twrmpc5125
by Rudy Cazeao 08 Jun '12

08 Jun '12

The latest version does not appear to contain support for the the twrmpc5125 processor because the following command issued in the u-boot installation directory yields nothing. $grep 5125 Makefile. My question is, how do you know which version of u-boot contains the most current source code with Freescale MPC5121e support that may be obtained from the DENX website. This source code would contain the most recent bug-fixes and feature updates. ________________________________ Technical data included in this e-mail may be Export-Controlled and subject to the Arms Export Control Act (Title 22, U.S.C., sec 2751 et seq.) or the Export Administration Act of 1979, as amended seq.

[U-Boot] [PATCH v3 0/5] kirkwood spi_claim/release_bus support
by Valentin Longchamp 07 Jun '12

07 Jun '12

This series adds generic support for the spi_claim/release_bus functions for the kirkwood processors. The implementation was already discussed in another thread following my first board specific submission of the patch. The series adds two functions to the kirkwood mpp code to be able to temporarily save and then restore the mpp configuration. Changes for v2: - save MPP configuration with mpp_read function as dicussed on ML - moved CS pin MPP config to spi_setup_slave only - add backup fo CS pin in spi_setup_slave and reset in spi_free_slave Changes for v3: - moved mpp_read function functionality into mpp_conf function - fixed all calls to mpp_conf so that they are compliant with the newly necessary mpp_conf prototype Valentin Longchamp (5): kirkwood: add save functionality kirkwood_mpp_conf function kirkwood: fix calls to kirkwood_mpp_conf kw_spi: backup and reset the MPP of the chosen CS pin kw_spi: support spi_claim/release_bus functions kw_spi: add weak functions board_spi_claim/release_bus arch/arm/cpu/arm926ejs/kirkwood/mpp.c | 14 ++++- arch/arm/include/asm/arch-kirkwood/mpp.h | 2 +- arch/arm/include/asm/arch-kirkwood/spi.h | 11 ++++ board/LaCie/net2big_v2/net2big_v2.c | 2 +- board/LaCie/netspace_v2/netspace_v2.c | 2 +- board/Marvell/dreamplug/dreamplug.c | 2 +- board/Marvell/guruplug/guruplug.c | 2 +- board/Marvell/mv88f6281gtw_ge/mv88f6281gtw_ge.c | 2 +- board/Marvell/openrd/openrd.c | 2 +- board/Marvell/rd6281a/rd6281a.c | 2 +- board/Marvell/sheevaplug/sheevaplug.c | 2 +- board/Seagate/dockstar/dockstar.c | 2 +- board/cloudengines/pogo_e02/pogo_e02.c | 2 +- board/d-link/dns325/dns325.c | 2 +- board/keymile/km_arm/km_arm.c | 6 +- board/raidsonic/ib62x0/ib62x0.c | 2 +- drivers/spi/kirkwood_spi.c | 64 +++++++++++++++++++---- 17 files changed, 93 insertions(+), 28 deletions(-)

[U-Boot] [PATCH] net: Multiple updates/enhancements to designware.c
by Stefan Roese 04 Jun '12

04 Jun '12

This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.

[U-Boot] [PATCH] tegra: override compiler flags for low level init code
by Allen Martin 04 Jun '12

04 Jun '12

Override -march setting for tegra to -march=armv4t for files that are necessary for low level init on tegra. The recent change to use -march=armv7-a for armv7 caused a regression on tegra because tegra starts boot on a arm7tdmi processor before transferring control to the cortex-a9. While still executing on the arm7tdmi there are calls to getenv_ulong() and memset() that cause an illegal instruction exception if compiled for armv7.
