[U-Boot] [PATCH 1/2] ARMv7: Factor out reusable timer_wait from sunxi/psci_sun7i.S
by Dongsheng Wang 21 Jul '15

21 Jul '15

From: Wang Dongsheng <dongsheng.wang(a)freescale.com> timer_wait is moved from sunxi/psci_sun7i.S, and it can be converted completely into a reusable armv7 generic timer. LS1021A will use it as well.

[U-Boot] [PATCH resend 1/3] mtd: nand: mxs support oobsize bigger than 512
by Peng Fan 21 Jul '15

21 Jul '15

If ecc chunk data size is 512 and oobsize is bigger than 512, there is a chance that block_mark_bit_offset conflicts with bch ecc area. The following graph is modified from kernel gpmi-nand.c driver with each data block 512 bytes. We can see that Block Mark conflicts with ecc area from bch view. We can enlarge the ecc chunk size to avoid this problem to those oobsize which is larger than 512. | P | |<----------------------------------------------------------------->| | | | (Block Mark) | | P' | | | | |<--------------------------------------------------->| D | | O'| | |<--------->| |<->| V V V V V +---+--------------+-+--------------+-+--------------+-+----------+-+---+ | M | data |E| data |E| data |E| data |E| | +---+--------------+-+--------------+-+--------------+-+----------+-+---+ ^ ^ | O | |<---------------->| P : the page size for BCH module. E : The ECC strength. G : the length of Galois Field. N : The chunk count of per page. M : the metasize of per page. C : the ecc chunk size, aka the "data" above. P': the nand chip's page size. O : the nand chip's oob size. O': the free oob.

[U-Boot] [PATCH] arm: ls1021a: Remove the inappropriate use of the function 'sprintf'
by Alison Wang 20 Jul '15

20 Jul '15

As the function 'sprintf' does not check buffer boundaries but outputs to the buffer 'enet' of fixed size (16), this patch removes the function 'sprintf', and uses 'strcpy' instead. It will assign the character arrays 'enet' and 'phy' the corresponding character strings.
