| | | | | | | | | | | | Erratum A-009663 workaround requires to set DDR_INTERVAL[BSTOPRE] to 0 before setting DDR_SDRAM_CFG[MEM_EN] and set DDR_INTERVAL[BSTOPRE] to the desired value after DDR initialization has completed. When DDR controller is configured to operate in auto-precharge mode(DDR_INTERVAL[BSTOPRE]=0), this workaround is not needed.

* ddr: altera: Replace float multiplication with integer oneMarek Vasut2015-08-231-1/+1
| | | | | | | | | | | | | | | | This gem is really really rare, there was an actual float used in the Altera DDR init code, which pulled in floating point ops from the libgcc, just wow. Since we don't support floating point operations the same way Linux does not support them, replace this with an integer multiplication and division combo. This removes some 2kiB of size from the SPL as the floating point ops are no longer pulled in from libgcc.

* arm: mvebu: sdram: Enable ECC support on Armada XPStefan Roese2015-08-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is tested on the DB-MV784MP-GP eval board. To really enable ECC support on this board the I2C EEPROM needs to get changed. As it saves the enabling of ECC support internally. For this the following commands can be used to enable ECC support on this board: Its recommended for first save (print) the value(s) in this EEPROM address: => i2c md 4e 0.1 2 0000: 05 00 .. To enable ECC support you need to set bit 1 in the 2nd byte: Marvell>> i2c mw 4e 1.1 02 Marvell>> i2c md 4e 0.1 2 0000: 05 02 .. To disable ECC support again, please use this command: Marvell>> i2c mw 4e 1.1 00 Marvell>> i2c md 4e 0.1 2 0000: 05 00 .. On other AXP boards, simply plugging an ECC DIMM should be enough to enable ECC support. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>

* ddr: altera: sdram: Make sdram_start and sdram_end into u32Marek Vasut2015-08-081-11/+12
| | | | | | | | | | | | | | | | Originally, both sdram_start and sdram_end were 64b values. The sdram_start had no reason for being so, since our address space is only 32b, so switching sdram_start to u32 is simple. The sdram_end is a bit more complex, since it can actually be set to (1 << 32) if someone really wanted to use an SoCFPGA with 4 GiB of DRAM and fixed the code around a little. But, the code handling the protection rules internally decrements the sdram_end variable anyway. Thus, instead of calling the code and passing in the address of the SDRAM end, pass in the address already decremented by one. This lets the sdram_end be 32b as well.
