[U-Boot] [PATCH v3 1/5] MIPS: Purple: Remove Purple support

daniel.schwierzeck at googlemail.com daniel.schwierzeck at googlemail.com
Mon Mar 28 18:33:54 CEST 2011


The Purple SoC and eval board are not actively maintained since years.
This patch removes the support completely as aggreed with Wolfgang Denk.

-Installation Instructions:
---------------------------
-
-1. Put the s2 switch into the following position:
-
-	Off On
-	------
-	|x   |
-	|   x|
-	|x   |
-	|   X|
-	------
-
-   Put the s3 switch into the following position:
-
-	Off On
-	------
-	| x  |
-	| x  |
-	|   x|
-	|   x|
-	------
-
-   Put the s4 switch into the following position:
-
-	Off On
-	------
-	|x   |
-	|x   |
-	|x   |
-	|x   |
-	|x   |
-	|   x|
-	|   x|
-	|x   |
-	------
-
-2. Connect to the serial console and to the BDI. Power on. On the
-   serial line, you should see:
-
-	PURPLE at 1.2>
-
-3. Type '8'. No echo will be displayed. In response, you should get:
-
-	7A(pass)
-
-4. From BDI, enter command:
-
-	mmw 0xb800d860 0x0042c7ff
-
-5. Then, from BDI:
-
-	erase 0xB0000000
-	erase 0xB0008000
-	erase 0xB000C000
-	erase 0xB0010000
-	erase 0xB0020000
-
-	prog 0xB0000000 <u-boot.bin> bin
-
-6. Power off. Restore the original S2 switch position:
-
-	Off On
-	------
-	|   x|
-	|   x|
-	|x   |
-	|   X|
-	------
-
-   Power on.  U-Boot should come up.
-
-
-Implementation Notes:
----------------------
-
-Due to the RAM/flash bus arbitration problem the suggested workaround
-had to be implemented. It works okay. On the downside is that you
-can't really check whether 'erase' is complete by polling flash as it
-is usually done. Instead, the flash driver simply waits for a given
-time and assumes that erase then has passed. This behaviour is
-identical to what the VxWorks driver does; also, the same timeout (6
-seconds) was chosen. Note that this timeout applies for each erase
-operation, i. e. per erased sector.
