| * mtd: cfi_cmdset_0002: Support Persistent Protection Bits (PPB) lockingStefan Roese2013-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently cfi_cmdset_0002.c does not support PPB locking of sectors. This patch adds support for this locking/unlocking mechanism. It is needed on some platforms, since newer U-Boot versions do support this PPB locking and protect for example their environment sector(s) this way. This PPB locking/unlocking will be enabled for all devices supported by cfi_cmdset_0002 reporting 8 in the CFI word 0x49 (Sector Protect/Unprotect scheme). Please note that PPB locking does support sector-by-sector locking. But the whole chip can only be unlocked together. So unlocking one sector will automatically unlock all sectors of this device. Because of this chip limitation, the PPB unlocking function saves the current locking status of all sectors before unlocking the whole device. After unlocking the saved locking status is re-configured. This way only the addressed sectors will be unlocked. To selectively enable this advanced sector protection mechanism, the device-tree property "use-advanced-sector-protection" has been created. To enable support for this locking this property needs to be present in the flash DT node. E.g.: nor_flash@0,0 { compatible = "amd,s29gl256n", "cfi-flash"; bank-width = <2>; use-advanced-sector-protection; ... Tested with Spansion S29GL512S10THI and Micron JS28F512M29EWx flash devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | This allows to put the filesystem at a defined address in ROM allowing to save more precious RAM. I think it's safe to default to ROM because the intention of using the uclinux map is to use a romfs and so mtd-ram doesn't give you anything that mtd-rom doesn't.

| | | | | | | | | | | | On some platforms (e.g. MPC5200) a direct 1:1 mapping may cause problems with JFFS2 usage, as the local bus (LPB) doesn't support unaligned accesses as implemented in the JFFS2 code via memcpy(). By defining "no-unaligned-direct-access", the flash will not be exposed directly to the MTD users (e.g. JFFS2) any more.

* mtd: allow uclinux map driver to be used on any ColdFire CPU platformGreg Ungerer2012-09-291-1/+1
| | | | | | | | | | | | | | | | | The uclinux.c map driver has traditionally been used only on non-MMU based systems. But there is no fundamental reason it can't be used on systems running with virtual memory. Some ColdFire CPU based systems now have full paged MMU hardware and can use the uclinux.c mapping driver, so making the uclinux.c driver configuration depend on !CONFIG_MMU doesn't make sense now. Allow the CONFIG_MTD_UCLINUX option to be enabled if CONFIG_COLDFIRE is enabled. (I have chosen not to just more generally allow uclinux.c for any MMU type to keep this option hidden for most systems that are not interested in setting it).

* mtd: fix wrong usage of ioremap_nocache() in uclinux.c map driverGreg Ungerer2012-09-291-6/+9
| | | | | | | | | | | | | | | | | | | | | | | The uclinux.c mapping driver uses ioremap_nocache() to map its physical mapping address to a system virtual address. Problem is that the region it is mapping is not device memory. It is ordinary system RAM. On most non-MMU systems this doesn't matter, and the mapping is always a 1:1 translation of the address. On paged memory systems on some architectures the page table mappings are not compatible between normal RAM and device memory. If we want to use the uclinux.c mapping driver on real MMU enabled systems we should be using the kernel virtual address that the mapping is at. For architectures that support the traditional initrd they use phys_to_virt or __va to convert the physical start initrd address to a kernel usable virtual address. The uclinux filesystem mapping is even more restrictive than the typical initrd, it always follows the kernels own bss section (so always in directly mapped memory). Therefore we can use the usual phys_to_virt to translate the physical start address to a virtual address.
