[U-Boot] [patch 0/2] Some more USB-OHCI bugfixes [V2]
by Remy Bohmer 01 Feb '10

01 Feb '10

This is version 2 of these series! Only patch 1 of 2 has changed, some pedantic Coding Style issues updated that were not detected by Linux/scripts/checkpatch.pl. The USB OHCI init procedure sets the maximum message length the wrong way. A max of 64 bits should not be done by writing '64' in maxpacketsize, but '3'. While fixing this problem it turned out that there is more wrong here in this code it turned out that the wrong bits were checked to determine if the pipe was of type PIPE_INTERRUPT. This series fixes those errors also. I made it 2 seperate patches. The 1st of this series is fully tested and correct on at least the AT91SAM9261 cores. The 2nd patch, however, is created by search-for-the-same-errors-and-replace. I am not able to test that patch, I do not have the boards, so that needs to be done by others or by review. It is clear that code there is buggy in the first place. These patches require my previous series called 'Improve stability USB memory sticks for the common OHCI USB layer.' to be applied before this series. So they should apply on the u-boot-usb git tree. --> git://git.denx.de/u-boot-usb.git I want to mention also, that everytime I look deeper into this code, I find new bugs. It appears that several parts of this code is written with interrupt handling in mind, while we have no interrupt handling at all. Assumptions are done that a interrupt handler does things asynchronous, causing long loops that have no real use at all... So, no guarantees that _all_ problems are solved by now... --

[U-Boot] [PATCH 1/5] tsec: Clean up Broadcom PHY status parsing
by Peter Tyser 27 Jan '10

27 Jan '10

- Remove unnecessary printing "Enet starting in <speed>/<duplex>" This same information is already printed during normal ethernet operation in the form "Speed: 1000, full duplex". - Add a check for link before determining link speed and duplex If there is no link, speed/duplex don't matter. This also removes the annoying and unneeded "Auto-neg error, defaulting to 10BT/HD" message that occurs when no link is detected. - Whitespace and line > 80 characters cleanup Signed-off-by: Peter Tyser <ptyser(a)xes-inc.com> --- drivers/net/tsec.c | 77 +++++++++++++++++++++++----------------------------- 1 files changed, 34 insertions(+), 43 deletions(-) diff --git a/drivers/net/tsec.c b/drivers/net/tsec.c index d8b6619..1038285 100644 --- a/drivers/net/tsec.c +++ b/drivers/net/tsec.c @@ -487,50 +487,41 @@ uint mii_BCM54xx_wirespeed(uint mii_reg, struct tsec_private *priv) */ uint mii_parse_BCM54xx_sr(uint mii_reg, struct tsec_private *priv) { + /* If there is no link, speed and duplex don't matter */ + if (!priv->link) + return 0; - switch((mii_reg & MIIM_BCM54xx_AUXSTATUS_LINKMODE_MASK) >> MIIM_BCM54xx_AUXSTATUS_LINKMODE_SHIFT){ - - case 1: - printf("Enet starting in 10BT/HD\n"); - priv->duplexity = 0; - priv->speed = 10; - break; - - case 2: - printf("Enet starting in 10BT/FD\n"); - priv->duplexity = 1; - priv->speed = 10; - break; - - case 3: - printf("Enet starting in 100BT/HD\n"); - priv->duplexity = 0; - priv->speed = 100; - break; - - case 5: - printf("Enet starting in 100BT/FD\n"); - priv->duplexity = 1; - priv->speed = 100; - break; - - case 6: - printf("Enet starting in 1000BT/HD\n"); - priv->duplexity = 0; - priv->speed = 1000; - break; - - case 7: - printf("Enet starting in 1000BT/FD\n"); - priv->duplexity = 1; - priv->speed = 1000; - break; - - default: - printf("Auto-neg error, defaulting to 10BT/HD\n"); - priv->duplexity = 0; - priv->speed = 10; - break; + switch ((mii_reg & MIIM_BCM54xx_AUXSTATUS_LINKMODE_MASK) >> + MIIM_BCM54xx_AUXSTATUS_LINKMODE_SHIFT) { + case 1: + priv->duplexity = 0; + priv->speed = 10; + break; + case 2: + priv->duplexity = 1; + priv->speed = 10; + break; + case 3: + priv->duplexity = 0; + priv->speed = 100; + break; + case 5: + priv->duplexity = 1; + priv->speed = 100; + break; + case 6: + priv->duplexity = 0; + priv->speed = 1000; + break; + case 7: + priv->duplexity = 1; + priv->speed = 1000; + break; + default: + printf("Auto-neg error, defaulting to 10BT/HD\n"); + priv->duplexity = 0; + priv->speed = 10; + break; } return 0; -- 1.6.2.1

[U-Boot] [PATCH] tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode
by Peter Tyser 27 Jan '10

27 Jan '10

In SGMII mode the link between a processor's internal TBI PHY and an external PHY should always be 1000Mbps, full duplex. Also, the SGMII interface between an internal TBI PHY and external PHY does not support in-band auto-negotation. Previously, when configured for SGMII mode a TBI PHY would attempt to restart auto-negotation during initializtion. This auto-negotation between a TBI PHY and external PHY would fail and result in unusable ethernet operation. Forcing the TBI PHY and and external PHY to link at 1000Mbps full duplex in SGMII mode resolves this issue of auto-negotation failing. Note that 10Mbps and 100Mbps operation is still possible on the external side of the external PHY even when SGMII is operating at 1000Mbps. The SGMII interface still operates at 1000Mbps, but each byte of data is repeated 100 or 10 times for 10/100Mbps and the external PHY handles converting this data stream into proper 10/100Mbps signalling. Signed-off-by: Peter Tyser <ptyser(a)xes-inc.com> --- In-band SGMII auto-negotiation doesn't work according to a lengthy discussion with a Freescale FAE and the AN3869 SGMII appnote. XES's MPC8572 and MPC8640 boards need this patch in order to use ethernet. These boards generally use SGMII to connect to an BCM5482S PHY which has an external gigabit-capable copper or fiber interface. Some of Freescale's reference platforms have an SGMII riser card - any idea how those function when using auto-negotiation? Do they function? Are the really using SGMII, or are they using 1000 Base-X? Some of the info in the manuals is misleading/confusing so any comments are more than welcome from Freescalers:) Thanks, Peter drivers/net/tsec.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers/net/tsec.c b/drivers/net/tsec.c index 3f74118..cff5d38 100644 --- a/drivers/net/tsec.c +++ b/drivers/net/tsec.c @@ -276,12 +276,13 @@ uint tsec_local_mdio_read(volatile tsec_t *phyregs, uint phyid, uint regnum) | TBIANA_FULL_DUPLEX \ ) +/* Force the TBI PHY into 1000Mbps full duplex when in SGMII mode */ #define TBICR_SETTINGS ( \ TBICR_PHY_RESET \ - | TBICR_ANEG_ENABLE \ | TBICR_FULL_DUPLEX \ | TBICR_SPEED1_SET \ ) + /* Configure the TBI for SGMII operation */ static void tsec_configure_serdes(struct tsec_private *priv) { -- 1.6.2.1

[U-Boot] [RFC PATCH] add ability to handle compressed images to imxtract

imxtract currently can not handle compressed images. This patch adds handling for bzip2 and zip compression. In both cases, a destination address has to be specified for extraction.
