* mpc8323erdb: Improve the system performanceMichael Barkowski2008-03-25-14/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are based on kernel UCC ethernet performance: 1. Make the CSB bus pipeline depth as 4, and enable the repeat mode 2. Optimize transactions between QE and CSB. Added CFG_SPCR_OPT switch to enable this setting. The following changes are based on the App Note AN3369 and verified to improve memory latency using LMbench: 3. CS0_CONFIG[AP_n_EN] is changed from 1 to 0 4. CS0_CONFIG[ODT_WR_CONFIG] set to 1. Was a reserved setting previously. 5. TIMING_CFG_1[WRREC] is changed from 3clks to 2clks (based on Twr=15ns, and this was already the setting in DDR_MODE) 6. TIMING_CFG_1[PRETOACT] is changed from 3clks to 2clks. (based on Trp=15ns) 7. TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 6clks. (based on Tras=40ns) 8. TIMING_CFG_1[ACTTORW] is changed from 3clks to 2clks. (based on Trcd=15ns) 9. TIMING_CFG_1[REFREC] changed from 21 clks to 11clks. (based on Trfc=75ns) 10. TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 7clks. (based on Tfaw=50ns) 11. TIMING_CFG_2[ADD_LAT] and DDR_MODE[AL] changed from 0 to 1 (based on CL=3 and WL=2).

* 83xx: Add Vitesse VSC7385 firmware uploadingTimur Tabi2008-03-25-71/+196
| | | | | | | | | | Update the MPC8349E-mITX, MPC8313E-RDB, and MPC837XE-RDB board files to upload the Vitesse VSC7385 firmware. Changed CONFIG_VSC7385 to CONFIG_VSC7385_ENET.

* NET: Add Vitesse VSC7385 firmware uploadingTimur Tabi2008-03-25-0/+115
| | | | | | | | | | | | | | | The Vitesse VSC7385 is a 5-port switch found on the Freescale MPC8349E-mITX and other boards. A small firwmare must be uploaded to its on-board memory before it can be enabled. This patch adds the code which uploads firmware (but not the firmware itself). Previously, this feature was provided by a U-Boot application that was made available only on Freescale BSPs. The VSC7385 firmware must still be obtained separately, but at least there is no longer a need for a separate application.

| | | | | | | | | | | | | | | | | | We do Hit_Writeback_Inv_D and Hit_Invalidate_I. You might think that you don't need to do Hit_Invalidate_I, but flush_cache() needs it since this function is used not only in U-Boot specfic programs but also at loading target binaries.

| * [MIPS] Fix I-/D-cache initialization loopsShinya Kuribayashi2008-03-25-39/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we do 1) Index_Store_Tag_I, 2) Fill and 3) Index_Store_Tag_I again per a loop for I-cache initialization. But according to 'See MIPS Run', we're encouraged to use three separate loops rather than combining them *for both I- and D-cache*. This patch tries to fix this. In accordance with fixing above, mips_init_[id]cache are separated from mips_cache_reset(), and rewrite cache loops are completely rewritten with useful macros.

| * [MIPS] Request for the 'mips_cache_lock()' removalShinya Kuribayashi2008-03-25-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial intension of having mips_cache_lock() was to use the cache as memory for temporary stack use so that a C environment can be set up as early as possible. But now mips_cache_lock() follow lowlevel_init(). We've already have the real memory initilaized at this point, therefore we could/should use it. No reason to lock at all. Other problems: Cache locking is not consistent across MIPS implementaions. Some imple- mentations don't support locking at all. The style of locking varies - some support per line locking, others per way, etc. Some parts use bits in status registers instead of cache ops. Current mips_cache_lock() is not necessarily general-purpose. And this is worthy of special mention; once U-Boot/MIPS locks the lines, they are never get unlocked, so the code relies on whatever gets loaded after U-Boot to re-initialize the cache and clear the locks. We're sup- posed to have CFG_INIT_RAM_LOCK and unlock_ram_in_cache() implemented, but leave the situation as it is for a long time. For these reasons, I proposed the removal of mips_cache_lock() from the global start-up code. This patch adds CFG_INIT_RAM_LOCK_MIPS to make existing users aware that *things have changed*. If he wants the same behavior as before, he needs to have CFG_INIT_RAM_LOCK_MIPS in his config file. If we don't have any regression report through several releases, then we'll remove codes entirely.

The conclusion of discussion on the u-boot email list was that embedding these in the fdt blob is not useful: there are better ways of passing the data (in fact, the fdt blob itself replaces the bd_t struct). The only board that enables these is the stxxtc and they don't appear to be used by linux. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com> Acked-by: Kim Phillips <kim.phillips@freescale.com>

* | Add Flex-OneNAND booting supportKyungmin Park2008-03-26-17/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array using a NOR Flash interface. This on-chip integration enables system designers to reduce external system logic and use high-density NAND Flash in applications that would otherwise have to use more NOR components. Flex-OneNAND enables users to configure to partition it into SLC and MLC areas in more flexible way. While MLC area of Flex-OneNAND can be used to store data that require low reliability and high density, SLC area of Flex-OneNAND to store data that need high reliability and high performance. Flex-OneNAND can let users take advantage of storing these two different types of data into one chip, which is making Flex-OneNAND more cost- and space-effective.
