From f060054dadbbe7027ca088eed806a3ef1f82fdb7 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 11 Jun 2008 00:44:10 -0500 Subject: FSL LAW: Keep track of LAW allocations Make it so we keep track of which LAWs have allocated and provide a function (set_next_law) which can allocate a LAW for us if one is free. In the future we will move to doing more "dynamic" LAW allocation since the majority of users dont really care about what LAW number they are at. Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them Signed-off-by: Kumar Gala Signed-off-by: Andy Fleming --- include/asm-ppc/fsl_law.h | 4 ++++ include/asm-ppc/global_data.h | 3 +++ 2 files changed, 7 insertions(+) (limited to 'include/asm-ppc') diff --git a/include/asm-ppc/fsl_law.h b/include/asm-ppc/fsl_law.h index e955c75..6c445a4 100644 --- a/include/asm-ppc/fsl_law.h +++ b/include/asm-ppc/fsl_law.h @@ -6,6 +6,9 @@ #define SET_LAW_ENTRY(idx, a, sz, trgt) \ { .index = idx, .addr = a, .size = sz, .trgt_id = trgt } +#define SET_LAW(a, sz, trgt) \ + { .index = -1, .addr = a, .size = sz, .trgt_id = trgt } + enum law_size { LAW_SIZE_4K = 0xb, LAW_SIZE_8K, @@ -70,6 +73,7 @@ struct law_entry { }; extern void set_law(u8 idx, phys_addr_t addr, enum law_size sz, enum law_trgt_if id); +extern int set_next_law(phys_addr_t addr, enum law_size sz, enum law_trgt_if id); extern void disable_law(u8 idx); extern void init_laws(void); extern void print_laws(void); diff --git a/include/asm-ppc/global_data.h b/include/asm-ppc/global_data.h index ea70266..8cf7b6f 100644 --- a/include/asm-ppc/global_data.h +++ b/include/asm-ppc/global_data.h @@ -96,6 +96,9 @@ typedef struct global_data { uint mp_alloc_base; uint mp_alloc_top; #endif /* CONFIG_QE */ +#if defined(CONFIG_FSL_LAW) + u32 used_laws; +#endif #if defined(CONFIG_MPC5xxx) unsigned long ipb_clk; unsigned long pci_clk; -- cgit v1.1
