- depends on ARCH_S3C2410 && PM && CRC32
- help
- Enable the PM code's memory area checksum over sleep. This option
- will generate CRCs of all blocks of memory, and store them before
- going to sleep. The blocks are then checked on resume for any
- errors.

- default 64
- help
- Set the chunksize in Kilobytes of the CRC for checking memory
- corruption over suspend and resume. A smaller value will mean that
- the CRC data block will take more memory, but wil identify any
- faults with better precision.

- Choice of which UART port to use for the low-level messages,

+ * Spec
+ *
+ * memcpy copies len bytes from src to dst and sets v0 to dst.
+ * It assumes that
+ * - src and dst don't overlap
+ * - src is readable
+ * - dst is writable
+ * memcpy uses the standard calling convention
+ *
+ * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
+ * the number of uncopied bytes due to an exception caused by a read or write.
+ * __copy_user assumes that src and dst don't overlap, and that the call is
+ * implementing one of the following:
+ * copy_to_user
+ * - src is readable (no exceptions when reading src)
+ * copy_from_user
+ * - dst is writable (no exceptions when writing dst)
+ * __copy_user uses a non-standard calling convention; see
+ * include/asm-mips/uaccess.h
+ *
+ * When an exception happens on a load, the handler must
+ # ensure that all of the destination buffer is overwritten to prevent
+ * leaking information to user mode programs.
+ */
+
+/*
+ * Implementation
+ */
+
+/*
+ * The exception handler for loads requires that:
+ * 1- AT contain the address of the byte just past the end of the source
+ * of the copy,
+ * 2- src_entry <= src < AT, and
+ * 3- (dst - src) == (dst_entry - src_entry),
+ * The _entry suffix denotes values when __copy_user was called.
+ *
+ * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
+ * (2) is met by incrementing src by the number of bytes copied
+ * (3) is met by not doing loads between a pair of increments of dst and src
+ *
+ * The exception handlers for stores adjust len (if necessary) and return.
+ * These handlers do not need to overwrite any data.
+ *
+ * For __rmemcpy and memmove an exception is always a kernel bug, therefore
+ * they're not protected.

+ * Generic heartbeat driver for regular LED banks
+ *
+ * Copyright (C) 2007 Paul Mundt
+ *
+ * Most SH reference boards include a number of individual LEDs that can
+ * be independently controlled (either via a pre-defined hardware
+ * function or via the LED class, if desired -- the hardware tends to
+ * encapsulate some of the same "triggers" that the LED class supports,
+ * so there's not too much value in it).
+ *
+ * Additionally, most of these boards also have a LED bank that we've
+ * traditionally used for strobing the load average. This use case is
+ * handled by this driver, rather than giving each LED bit position its
+ * own struct device.

- * New Funky TSC sync algorithm borrowed from IA64.
- * Main advantage is that it doesn't reset the TSCs fully and
- * in general looks more robust and it works better than my earlier
- * attempts. I believe it was written by David Mosberger. Some minor
- * adjustments for x86-64 by me -AK
- *
- * Original comment reproduced below.
- *
- * Synchronize TSC of the current (slave) CPU with the TSC of the
- * MASTER CPU (normally the time-keeper CPU). We use a closed loop to
- * eliminate the possibility of unaccounted-for errors (such as
- * getting a machine check in the middle of a calibration step). The
- * basic idea is for the slave to ask the master what itc value it has
- * and to read its own itc before and after the master responds. Each
- * iteration gives us three timestamps:
- *
- * slave master
- *
- * t0 ---\
- * ---\
- * --->
- * tm
- * /---
- * /---
- * t1 <---
- *
- *
- * The goal is to adjust the slave's TSC such that tm falls exactly
- * half-way between t0 and t1. If we achieve this, the clocks are
- * synchronized provided the interconnect between the slave and the
- * master is symmetric. Even if the interconnect were asymmetric, we
- * would still know that the synchronization error is smaller than the
- * roundtrip latency (t0 - t1).
- *
- * When the interconnect is quiet and symmetric, this lets us
- * synchronize the TSC to within one or two cycles. However, we can
- * only *guarantee* that the synchronization is accurate to within a
- * round-trip time, which is typically in the range of several hundred
- * cycles (e.g., ~500 cycles). In practice, this means that the TSCs
- * are usually almost perfectly synchronized, but we shouldn't assume
- * that the accuracy is much better than half a micro second or so.
- *
- * [there are other errors like the latency of RDTSC and of the
- * WRMSR. These can also account to hundreds of cycles. So it's
- * probably worse. It claims 153 cycles error on a dual Opteron,
- * but I suspect the numbers are actually somewhat worse -AK]
