[U-Boot-Users] SATA patch.

[U-Boot-Users] SATA patch.

[mushtaq khan]

Hi,

I have attach a patch, for a SATA controller of Intel processor with 
South Bridge ICH5, ICH6 and ICH7. These chipset's don't support AHCI, 
and so you cann't use the driver ahci.c in u-boot code.
I have divided the code into two files, functions which are controller 
specifc are kept in ata-piix.c under directory drivers(this is with 
reference to ata-piix driver in kernel). And functions which are common 
to Sata controllers are kept in cmd_sata.c, under directory common (this 
is with reference to libata in kernel and cmd_ide.c in u-boot).

Thanks,
Mushtaq khan.

I started reading through this and quickly gave up.  Please address the
following before re-submitting:

1.  General coding standards violations:
	line lengths < 78 characters
	No '#if 0' or '#if 1'
	Keep blank lines to a readable minimum
	No C++ style comments
	blah, blah, blah - read the guidelines

2.  The only files you should send are patches.  The others are
superfluous.  Changelog isn't necessary and the other one should either
be in the e-mail or as a README

3.  Please use a .diff or .patch filename extension.  Text editors often
key syntax highlighting and other things from extensions.

Please read the following.  It will help you format your submission.

[U-Boot-Users] Bad u-boot ETHERLITE driver performance.

[Leonid]

Hi:

On Xilinx Spartan-3e Starter Kit during uClinux image downloading from
u-boot via TFTP some packets get lost slower down downloading process.

This is typical downloading snapshot:

U-Boot> tftp 23000000 lm125/rel/1.0.0/image.ub
TFTP from server 192.168.0.141; our IP address is 192.168.0.206 Filename
'lm125/rel/1.0.0/image.ub'. Load address: 0x23000000
Loading:
#################################################################

###################T 
         ###############################################################
done
Bytes transferred = 3313728 (329040 hex)
U-Boot>

This is happening only with ETHERNETLITE core and never with EMAC core
(network setup is precisely the same). Also as soon as uClinux is
loaded, network applications (including NFS and TFTP) are working
smoothly meaning that problem is in u-boot emaculite drivers themselves
(I'm using u-boot 1.1.4 snapshot from Petalinux distro). 

Wolfgang Denk suggested here
http://www.denx.de/wiki/view/DULG/TFTPTimeout that it can be problem
with full/half duplex configuration, but I couldn't find how to
configure such mode is configured for emaculite driver.

Please advise,

Leonid.

[U-Boot-Users] SATA PATCH

[mushtaq khan]

Hi,

I am resending the patch with proper indentation. This patch is for SATA 
controllers of Intel processor with South bridge ICH5,ICH6 and ICH7. 
These chipsets don't support AHCI interface.

Code is divided in to two files. One file has functions which are 
specific to controller and another file which has functions, which are 
common to most of the Sata controllers.

[U-Boot-Users] SATA PATCH

Dear Mushtaq,

Thanks. The patch has a few coding style issues: indentation by space
instead of TABs, trailing white space, etc.

Please see http://www.denx.de/wiki/UBoot/CodingStyle

Please insert a few more spaces, i. e. instead of 

	}else if(strcmp(argv[1],"part") == 0){
write:
	} else if (strcmp(argv[1],"part") == 0) {

In a few places your indentation looks random, like here:

	printf ("%ld blocks written: %s\n",
	                                        n, (n==cnt) ? "OK" : "ERROR");

Please use only lower case letters for the command name, i. e. "sata"
instead of "Sata".

In common/Makefile and drivers/Makefile,  please  keep  the  list  of
object file names alphabetically sorted.

Please clean up and resubmit.

Best regards,

Wolfgang Denk

Hi ,
    I have done the indentation by running the script "Lindent" of linux 
source code with -pcs  option.

Thanks,
-Mushtaq Khan.
